of/irq: Fix using uninitialized variable @addr_len in API of_irq_parse_one()
of_irq_parse_one() may use uninitialized variable @addr_len as shown below:
// @addr_len is uninitialized
int addr_len;
// This operation does not touch @addr_len if it fails.
addr = of_get_property(device, "reg", &addr_len);
// Use uninitialized @addr_len if the operation fails.
if (addr_len > sizeof(addr_buf))
addr_len = sizeof(addr_buf);
// Check the operation result here.
if (addr)
memcpy(addr_buf, addr, addr_len);
Fix by initializing @addr_len before the operation.

On a malformed interrupt-map property which is shorter than expected by
1 cell, we may read bogus data past the end of the property instead of

of: Fix refcount leakage for OF node returned by __of_get_dma_parent()
__of_get_dma_parent() returns OF device node @args.np, but the node's
refcount is increased twice, by both of_parse_phandle_with_args() and
of_node_get(), so causes refcount leakage for the node.
Fix by directly returning the node got by of_parse_phandle_with_args().

of/irq: Correct element count for array @dummy_imask in API of_irq_parse_raw()
Array @dummy_imask only needs MAX_PHANDLE_ARGS elements, but it actually has (MAX_PHANDLE_ARGS + 1) elements. One extra element doesn't hurt anything except for some stack usage.

of: Fix error path in of_parse_phandle_with_args_map()
The current code uses some 'goto put;' to cancel the parsing operation
and can lead to a return code value of 0 even on error cases.
Indeed, some goto calls are done from a loop without setting the ret
value explicitly before the goto call and so the ret value can be set to
0 due to operation done in previous loop iteration. For instance match
can be set to 0 in the previous loop iteration (leading to a new
iteration) but ret can also be set to 0 it the of_property_read_u32()
call succeed. In that case if no match are found or if an error is
detected the new iteration, the return value can be wrongly 0.
Avoid those cases setting the ret value explicitly before the goto
calls.

of: Add #address-cells/#size-cells in the device-tree root empty node
On systems where ACPI is enabled or when a device-tree is not passed to the kernel by the bootloader, a device-tree root empty node is created. This device-tree root empty node does not have the #address-cells and the #size-cells properties This leads to the use of the default address cells and size cells values which are defined in the code to 1 for the address cells value and 1 for the size cells value. According to the devicetree specification and the OpenFirmware standard (IEEE 1275-1994) the default value for #address-cells should be 2. Also, according to the devicetree specification, the #address-cells and the #size-cells are required properties in the root node. The device tree compiler already uses 2 as default value for address cells and 1 for size cells. The powerpc PROM code also uses 2 as default value for address cells and 1 for size cells. Modern implementation should have the #address-cells and the #size-cells properties set and should not rely on default values. On x86, this root empty node is used and the code default values are used. In preparation of the support for device-tree overlay on PCI devices feature on x86 (i.e. the creation of the PCI root bus device-tree node), the default value for #address-cells needs to be updated. Indeed, on x86_64, addresses are on 64bits and the upper part of an address is needed for correct address translations. On x86_32 having the default value updated does not lead to issues while the upper part of a 64-bit value is zero. Changing the default value for all architectures may break device-tree compatibility. Indeed, existing dts file without the #address-cells property set in the root node will not be compatible with this modification. Instead of updating default values, add both required #address-cells and #size-cells properties in the device-tree empty node. Use 2 for both properties value in order to fully support 64-bit addresses and sizes on systems using this empty root node.

Get rid of 'remove_new' relic from platform driver struct
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

core: add of based component probing Some devices are designed and manufactured with some components having multiple drop-in replacement options. These components are often connected to the mainboard via ribbon cables, having the same signals and pin assignments across all options. These may include the display panel and touchscreen on laptops and tablets, and the trackpad on laptops. Sometimes which component option is used in a particular device can be detected by some firmware provided identifier, other times that information is not available, and the kernel has to try to probe each device. Instead of a delicate dance between drivers and device tree quirks, this change introduces a simple I2C component probe function. For a given class of devices on the same I2C bus, it will go through all of them, doing a simple I2C read transfer and see which one of them responds. It will then enable the device that responds. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEOZGx6rniZ1Gk92RdFA3kzBSgKbYFAmdMOCwACgkQFA3kzBSg KbaLWQ//e+29c9Trh+Typ6YCknuCFmM12xNUEPgce93EldERZjfCsdlHEchJnjEe RX5Mw+UxT7NqFUD6G2YQQw35LMj/PDws4Q/q3OwAvurj2PqoKEGIbdTxUEbGrLtT aYRUjGoqjPk3gAkqfKEQp8X8bvqKJfQ/xeXcZyy7Ij8xPU1LC/W6So4vpZA7oZkZ UfwrUXu2NM/DKfLATeSH3vnlBrrpco9BdjImDanP8BpuYHQ0aNt7IToDytd3/rLZ WKQPbHqVzzBUHm8Tf+DTyeVtII/ID078z+RW7htPrzPtzhVu2DN56w3z7/+EsVIy XKb1PiJo5HlFev4gxhIcUgf8L5JYE8MyU8eeRWAcDObiBYVcSP34P7Xoykczjuq9 22IFNSdaqMVdigo9v4p7U99fVjoi3oUqIVsSb2HkmND8bPw3+jtyq1GxTFvTeOw8 EVJGuGjYrPiko26zNgK/WZaumpB+fsH7uRioSb1ejlSQk0BcNv4YqjYaMx9aT7Xj +zF7luuxpkWTkPCjk57GX55K/BFzkA9jhJdKqjImBS+Q9Rn3k5bHyRdNPUDIeWs0 Yl5dhg6QbLHyuPC2R/hJiV6X4uFloH9+Oh99T3lLzcVNc2mllPQDN9F4I8q5nWB8 Eq5U95fnegfdVkiWnbNCnTCux/mypm35Gx46BffTiAJL2U9pSIE= =MAxU -----END PGP SIGNATURE----- Merge tag 'i2c-for-6.13-rc1-part3' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c component probing support from Wolfram Sang: "Add OF component probing.

of: address: Preserve the flags portion on 1:1 dma-ranges mapping
A missing or empty dma-ranges in a DT node implies a 1:1 mapping for dma
translations. In this specific case, the current behaviour is to zero out
the entire specifier so that the translation could be carried on as an
offset from zero. This includes address specifier that has flags (e.g.
PCI ranges).
Once the flags portion has been zeroed, the translation chain is broken
since the mapping functions will check the upcoming address specifier
against mismatching flags, always failing the 1:1 mapping and its entire
purpose of always succeeding.
Set to zero only the address portion while passing the flags through.

anything besides making it easier to run the tests without them
skipping. Remove the select and move the config setting to the

of/address: Rework bus matching to avoid warnings
With warnings added for deprecated #address-cells/#size-cells handling, the DT address handling code causes warnings when used on nodes with no address. This happens frequently with calls to of_platform_populate() as it is perfectly acceptable to have devices without a 'reg' property. The desired behavior is to just silently return an error when retrieving an address. The warnings can be avoided by checking for "#address-cells" presence first and checking for an address property before fetching "#address-cells" and "#size-cells".

It's been a warning in dtc for the root node since the beginning (2005) and for any parent node since 2007. Of course, not all FDT uses dtc, but that should be the majority by far. The various extracted OF devicetrees I have dating back to the 1990s (various PowerMac, OLPC, PASemi Nemo) all have explicit root node properties. The warning is disabled for Sparc as there are known systems relying on default root node values.

kbuild: add generic support for built-in boot DTBs
Some architectures embed boot DTBs in vmlinux. A potential issue for these architectures is a race condition during parallel builds because Kbuild descends into arch/*/boot/dts/ twice. One build thread is initiated by the 'dtbs' target, which is a prerequisite of the 'all' target in the top-level Makefile: ifdef CONFIG_OF_EARLY_FLATTREE all: dtbs endif For architectures that support the built-in boot dtb, arch/*/boot/dts/ is visited also during the ordinary directory traversal in order to build obj-y objects that wrap DTBs. Since these build threads are unaware of each other, they can run simultaneously during parallel builds. This commit introduces a generic build rule to scripts/Makefile.vmlinux to support embedded boot DTBs in a race-free way. Architectures that want to use this rule need to select CONFIG_GENERIC_BUILTIN_DTB. After the migration, Makefiles under arch/*/boot/dts/ will be visited only once to build only *.dtb files. This change also aims to unify the CONFIG options used for built-in DTBs support. Currently, different architectures use different CONFIG options for the same purposes. With this commit, the CONFIG options will be unified as follows: - CONFIG_GENERIC_BUILTIN_DTB This enables the generic rule for built-in boot DTBs. This will be renamed to CONFIG_BUILTIN_DTB after all architectures migrate to the generic rule. - CONFIG_BUILTIN_DTB_NAME This specifies the path to the embedded DTB. (relative to arch/*/boot/dts/) - CONFIG_BUILTIN_DTB_ALL If this is enabled, all DTB files compiled under arch/*/boot/dts/ are embedded into vmlinux. Only used by MIPS.

of/fdt: add dt_phys arg to early_init_dt_scan and early_init_dt_verify
__pa() is only intended to be used for linear map addresses and using
it for initial_boot_params which is in fixmap for arm64 will give an
incorrect value. Hence save the physical address when it is known at
boot time when calling early_init_dt_scan for arm64 and use it at kexec
time instead of converting the virtual address using __pa().
Note that arm64 doesn't need the FDT region reserved in the DT as the

of: property: add of_graph_get_next_port_endpoint()
We already have of_graph_get_next_endpoint(), but it is not
intuitive to use in some case.
(X) node {
(Y) ports {
(P0) port@0 { endpoint { remote-endpoint = ...; };};
(P10) port@1 { endpoint { remote-endpoint = ...; };
(P11) endpoint { remote-endpoint = ...; };};
(P2) port@2 { endpoint { remote-endpoint = ...; };};
};
};
For example, if I want to handle port@1's 2 endpoints (= P10, P11),
I want to use like below
P10 = of_graph_get_next_endpoint(port1, NULL);
P11 = of_graph_get_next_endpoint(port1, P10);
But 1st one will be error, because of_graph_get_next_endpoint()
requested 1st parameter is "node" (X) or "ports" (Y), not but "port".
Below works well, but it will get P0
P0 = of_graph_get_next_endpoint(node, NULL);
P0 = of_graph_get_next_endpoint(ports, NULL);
In other words, we can't handle P10/P11 directly via
of_graph_get_next_endpoint().
There is another non intuitive behavior on of_graph_get_next_endpoint().
In case of if I could get P10 pointer for some way, and if I want to
handle port@1 things by loop, I would like use it like below
/*
* "ep" is now P10, and handle port1 things here,
* but we don't know how many endpoints port1 have.
*
* Because "ep" is non NULL now, we can use port1
* as of_graph_get_next_endpoint(port1, xxx)
*/
do {
/* do something for port1 specific things here */
} while (ep = of_graph_get_next_endpoint(port1, ep))
But it also not worked as I expected.
I expect it will be P10 -> P11 -> NULL,
but it will be P10 -> P11 -> P2, because
of_graph_get_next_endpoint() will fetch "endpoint" beyond the "port".
It is not useful for generic driver.
To handle endpoint more intuitive, create of_graph_get_next_port_endpoint()
of_graph_get_next_port_endpoint(port1, NULL); // P10
of_graph_get_next_port_endpoint(port1, P10); // P11
of_graph_get_next_port_endpoint(port1, P11); // NULL

of: property: add of_graph_get_next_port()
We have endpoint base functions
- of_graph_get_next_endpoint()
- of_graph_get_endpoint_count()
- for_each_endpoint_of_node()
Here, for_each_endpoint_of_node() loop finds each endpoints
ports {
port@0 {
(1) endpoint {...};
};
port@1 {
(2) endpoint {...};
};
...
};
In above case, it finds endpoint as (1) -> (2) -> ...
Basically, user/driver knows which port is used for what, but not in
all cases. For example on flexible/generic driver case, how many ports
are used is not fixed.
For example Sound Generic Card driver which is very flexible/generic and
used from many venders can't know how many ports are used, and used for
what, because it depends on each vender SoC and/or its used board.
And more, the port can have multi endpoints. For example Generic Sound
Card case, it supports many type of connection between CPU / Codec, and
some of them uses multi endpoint in one port. see below.
ports {
(A) port@0 {
(1) endpoint@0 {...};
(2) endpoint@1 {...};
};
(B) port@1 {
(3) endpoint {...};
};
...
};
Generic Sound Card want to handle each connection via "port" base instead
of "endpoint" base. But, it is very difficult to handle each "port" via
existing for_each_endpoint_of_node(). Because getting each "port" via
of_get_parent() from each "endpoint" doesn't work. For example in above
case, both (1) (2) endpoint has same "port" (= A).
Add "port" base functions.

of: reserved_mem: Add code to dynamically allocate reserved_mem array
The reserved_mem array is statically allocated with a size of MAX_RESERVED_REGIONS(64). Therefore, if the number of reserved_mem regions exceeds this size, there will not be enough space to store all the data. Hence, extend the use of the static array by introducing a dynamically allocated array based on the number of reserved memory regions specified in the DT. On architectures such as arm64, memblock allocated memory is not writable until after the page tables have been setup. Hence, the dynamic allocation of the reserved_mem array will need to be done only after the page tables have been setup. As a result, a temporary static array is still needed in the initial stages to store the information of the dynamically-placed reserved memory regions because the start address is selected only at run-time and is not stored anywhere else. It is not possible to wait until the reserved_mem array is allocated because this is done after the page tables are setup and the reserved memory regions need to be initialized before then. After the reserved_mem array is allocated, all entries from the static array is copied over to the new array, and the rest of the information for the statically-placed reserved memory regions are read in from the DT and stored in the new array as well. Once the init process is completed, the temporary static array is released back to the system because it is no longer needed. This is achieved by marking it as __initdata.

of: reserved_mem: Restructure how the reserved memory regions are processed
Reserved memory regions defined in the devicetree can be broken up into
two groups:
i) Statically-placed reserved memory regions
i.e. regions defined with a static start address and size using the
"reg" property.
ii) Dynamically-placed reserved memory regions.
i.e. regions defined by specifying an address range where they can be
placed in memory using the "alloc_ranges" and "size" properties.
These regions are processed and set aside at boot time.
This is done in two stages as seen below:
Stage 1:
At this stage, fdt_scan_reserved_mem() scans through the child nodes of
the reserved_memory node using the flattened devicetree and does the
following:
1) If the node represents a statically-placed reserved memory region,
i.e. if it is defined using the "reg" property:
- Call memblock_reserve() or memblock_mark_nomap() as needed.
- Add the information for that region into the reserved_mem array
using fdt_reserved_mem_save_node().
i.e. fdt_reserved_mem_save_node(node, name, base, size).
2) If the node represents a dynamically-placed reserved memory region,
i.e. if it is defined using "alloc-ranges" and "size" properties:
- Add the information for that region to the reserved_mem array with
the starting address and size set to 0.
i.e. fdt_reserved_mem_save_node(node, name, 0, 0).
Note: This region is saved to the array with a starting address of 0
because a starting address is not yet allocated for it.
Stage 2:
After iterating through all the reserved memory nodes and storing their
relevant information in the reserved_mem array,fdt_init_reserved_mem() is
called and does the following:
1) For statically-placed reserved memory regions:
- Call the region specific init function using
__reserved_mem_init_node().
2) For dynamically-placed reserved memory regions:
- Call __reserved_mem_alloc_size() which is used to allocate memory
for each of these regions, and mark them as nomap if they have the
nomap property specified in the DT.
- Call the region specific init function.
The current size of the resvered_mem array is 64 as is defined by
MAX_RESERVED_REGIONS. This means that there is a limitation of 64 for
how many reserved memory regions can be specified on a system.
As systems continue to grow more and more complex, the number of
reserved memory regions needed are also growing and are starting to hit
this 64 count limit, hence the need to make the reserved_mem array
dynamically sized (i.e. dynamically allocating memory for the
reserved_mem array using membock_alloc_*).
On architectures such as arm64, memory allocated using memblock is
writable only after the page tables have been setup. This means that if
the reserved_mem array is going to be dynamically allocated, it needs to
happen after the page tables have been setup, not before.
Since the reserved memory regions are currently being processed and
added to the array before the page tables are setup, there is a need to
change the order in which some of the processing is done to allow for
the reserved_mem array to be dynamically sized.
It is possible to process the statically-placed reserved memory regions
without needing to store them in the reserved_mem array until after the
page tables have been setup because all the information stored in the
array is readily available in the devicetree and can be referenced at
any time.
Dynamically-placed reserved memory regions on the other hand get
assigned a start address only at runtime, and hence need a place to be
stored once they are allocated since there is no other referrence to the
start address for these regions.
Hence this patch changes the processing order of the reserved memory
regions in the following ways:
Step 1:
fdt_scan_reserved_mem() scans through the child nodes of
the reserved_memory node using the flattened devicetree and does the
following:
1) If the node represents a statically-placed reserved memory region,
i.e. if it is defined using the "reg" property:
- Call memblock_reserve() or memblock_mark_nomap() as needed.
2) If the node represents a dynamically-placed reserved memory region,
i.e. if it is defined using "alloc-ranges" and "size" properties:
- Call __reserved_mem_alloc_size() which will:
i) Allocate memory for the reserved region and call
memblock_mark_nomap() as needed.
ii) Call the region specific initialization function using
fdt_init_reserved_mem_node().
iii) Save the region information in the reserved_mem array using
fdt_reserved_mem_save_node().
Step 2:
1) This stage of the reserved memory processing is now only used to add
the statically-placed reserved memory regions into the reserved_mem
array using fdt_scan_reserved_mem_reg_nodes(), as well as call their
region specific initialization functions.
2) This step has also been moved to be after the page tables are
setup. Moving this will allow us to replace the reserved_mem
array with a dynamically sized array before storing the rest of
these regions.

The core clk framework is left largely untouched this time around except for
support for the newly ratified DT property 'assigned-clock-rates-u64'. I'm much
more excited about the support for loading DT overlays from KUnit tests so that
we can test how the clk framework parses DT nodes during clk registration. The
clk framework has some places that are highly DeviceTree dependent so this
charts the path to extend the KUnit tests to cover even more framework code in
the future. I've got some more tests on the list that use the DT overlay
support, but they uncovered issues with clk unregistration that I'm still
working on fixing.
Outside the core, the clk driver update pile is dominated by Qualcomm and
Renesas SoCs, making it fairly usual. Looking closer, there are fixes for
things all over the place, like adding missing clk frequencies or moving
defines for the number of clks out of DT binding headers into the drivers.
There are even conversions of DT bindings to YAML and migration away from
strings to describe clk topology. Overall it doesn't look unusual so I expect
the new drivers to be where we'll have fixes in the coming weeks.
Core:
- KUnit tests for clk registration and fixed rate basic clk type
- A couple more devm helpers, one consumer and one provider

kstack_8k 243
kstack_16k 0
which tells us that 11391 processes used 4k of stack while none at all
used 16k. Useful for some system tuning things, but partivularly useful
for "the dynamic kernel stack project".
"kmemleak: support for percpu memory leak detect" from Pavel Tikhomirov.
Teaches kmemleak to detect leaksage of percpu memory.

tuning to improve zswap's dynamic shrinker. Significant reductions in
swapin and improvements in performance are shown.
"mm: Fix several issues with unaccepted memory" from Kirill Shutemov.
Improvements to the new unaccepted memory feature,
"mm/mprotect: Fix dax puds" from Peter Xu. Implements mprotect on DAX
PUDs. This was missing, although nobody seems to have notied yet.
"Introduce a store type enum for the Maple tree" from Sidhartha Kumar.
Cleanups and modest performance improvements for the maple tree library
code.
"memcg: further decouple v1 code from v2" from Shakeel Butt. Move more
cgroup v1 remnants away from the v2 memcg code.
"memcg: initiate deprecation of v1 features" from Shakeel Butt. Adds
various warnings telling users that memcg v1 features are deprecated.
"mm: swap: mTHP swap allocator base on swap cluster order" from Chris Li.
Greatly improves the success rate of the mTHP swap allocation.
"mm: introduce numa_memblks" from Mike Rapoport. Moves various disparate
per-arch implementations of numa_memblk code into generic code.
"mm: batch free swaps for zap_pte_range()" from Barry Song. Greatly
improves the performance of munmap() of swap-filled ptes.
"support large folio swap-out and swap-in for shmem" from Baolin Wang.
With this series we no longer split shmem large folios into simgle-page
folios when swapping out shmem.
"mm/hugetlb: alloc/free gigantic folios" from Yu Zhao. Nice performance
improvements and code reductions for gigantic folios.
"support shmem mTHP collapse" from Baolin Wang. Adds support for
khugepaged's collapsing of shmem mTHP folios.
"mm: Optimize mseal checks" from Pedro Falcato. Fixes an mprotect()
performance regression due to the addition of mseal().
"Increase the number of bits available in page_type" from Matthew Wilcox.
Increases the number of bits available in page_type!
"Simplify the page flags a little" from Matthew Wilcox. Many legacy page
flags are now folio flags, so the page-based flags and their
accessors/mutators can be removed.
"mm: store zero pages to be swapped out in a bitmap" from Usama Arif. An
optimization which permits us to avoid writing/reading zero-filled zswap
pages to backing store.

of, numa: return -EINVAL when no numa-node-id is found
Currently of_numa_parse_memory_nodes() returns 0 if no "memory" node in device tree contains "numa-node-id" property. This makes of_numa_init() to return "success" despite no NUMA nodes were actually parsed and set up. arch_numa workarounds this by returning an error if numa_nodes_parsed is empty. numa_memblks however would WARN() in such case and since it will be used by arch_numa shortly, such warning is not desirable. Make sure of_numa_init() returns -EINVAL when no NUMA node information was found in the device tree.

video/aperture: optionally match the device in sysfb_disable()
In aperture_remove_conflicting_pci_devices(), we currently only
call sysfb_disable() on vga class devices. This leads to the
following problem when the pimary device is not VGA compatible:
1. A PCI device with a non-VGA class is the boot display
2. That device is probed first and it is not a VGA device so
sysfb_disable() is not called, but the device resources
are freed by aperture_detach_platform_device()
3. Non-primary GPU has a VGA class and it ends up calling sysfb_disable()
4. NULL pointer dereference via sysfb_disable() since the resources
have already been freed by aperture_detach_platform_device() when
it was called by the other device.
Fix this by passing a device pointer to sysfb_disable() and checking
the device to determine if we should execute it or not.
v2: Fix build when CONFIG_SCREEN_INFO is not set
v3: Move device check into the mutex
Drop primary variable in aperture_remove_conflicting_pci_devices()
Drop __init on pci sysfb_pci_dev_is_enabled()
Fixes:

of: Add a KUnit test for overlays and test managed APIs
Test the KUnit test managed overlay APIs. Confirm that platform devices are created and destroyed properly.

of: Add test managed wrappers for of_overlay_apply()/of_node_put()
Add test managed wrappers for of_overlay_apply() that automatically
removes the overlay when the test is finished. This API is intended for
use by KUnit tests that test code which relies on 'struct device_node's
and of_*() APIs.
KUnit tests will call of_overlay_apply_kunit() to load an overlay that's
been built into the kernel image. When the test is complete, the overlay
will be removed.
This has a few benefits:
1) It keeps the tests hermetic because the overlay is removed when the
test is complete. Tests won't even be aware that an overlay was
loaded in another test.
2) The overlay code can live right next to the unit test that loads it.
The overlay and the unit test can be compiled into one kernel module
if desired.
3) We can test different device tree configurations by loading
different overlays. The overlays can be written for a specific test,
and there can be many of them loaded per-test without needing to jam
all possible combinations into one DTB.
4) It also allows KUnit to test device tree dependent code on any
architecture, not just UML. This allows KUnit tests to test
architecture specific device tree code.
There are some potential pitfalls though. Test authors need to be
careful to not overwrite properties in the live tree. The easiest way to
do this is to add and remove nodes with a 'kunit-' prefix, almost
guaranteeing that the same node won't be present in the tree loaded at
boot.

of/platform: Allow overlays to create platform devices from the root node
We'd like to apply overlays to the root node in KUnit so we can test platform devices created as children of the root node. On some architectures (powerpc), the root node isn't marked with OF_POPULATED_BUS. If an overlay tries to modify the root node on these platforms it will fail, while on other platforms, such as ARM, it will succeed. This is because the root node is marked with OF_POPULATED_BUS by of_platform_default_populate_init() calling of_platform_default_populate() with NULL as the first argument. Loosen the requirement here so that platform devices can be created for nodes created as children of the root node via DT overlays even if the platform bus wasn't populated for the root node.

of/irq: Factor out parsing of interrupt-map parent phandle+args from of_irq_parse_raw()
Factor out the parsing of interrupt-map interrupt parent phandle and its arg cells to a separate function, of_irq_parse_imap_parent(), so that it can be used in other parsing scenarios (e.g. fw_devlink). There was a refcount leak on non-matching entries when iterating thru "interrupt-map" which is fixed.

Networking changes for 6.10.
Core & protocols
----------------
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd passing
functionality. New method based on Tarjan's Strongly Connected Components
algorithm should be both faster and remove a lot of workarounds
we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP packets
and forwarding them together. Useful for small switches / routers which
lack basic checksum offload in some scenarios (e.g. PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't
use NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address
labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files,
MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs,
neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link
information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory accounting,
RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2% PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked,
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states.
State can be used either for input or output packet processing.
Things we sprinkled into general kernel code
--------------------------------------------
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter
---------
- Use GFP_KERNEL to clone elements, to deal better with OOM situations
and avoid failures in the .commit step.
BPF
---
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function entry
and return, the entry program can decide if the return program gets
executed and the entry program can share u64 cookie value with return
program. "Session mode" is a common use-case for tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw tracepoint
programs in order to ease migration from classic to raw tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V JITs.
This allows inlining functions which need to access per-CPU state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86 instruction.
Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor process-context
bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API
----------
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line) config.
- Initial bits of a queue control API, for now allowing a single queue
to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling
-----------------
- Remove the need to create a config file to run the net forwarding tests
so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test machine).
Add a few such tests.
- Create a shared code library for writing Python tests. Expose the YAML
Netlink library from tools/ to the tests for easy Netlink access.
- Move netfilter tests under net/, extend them, separate performance tests
from correctness tests, and iron out issues found by running them
"on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF info,
TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers
-------
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application rather
than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen).
- Ethernet high-speed NICs:
- Broadcom (bnxt):

Merge tag 'net-next-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Complete rework of garbage collection of AF_UNIX sockets.
AF_UNIX is prone to forming reference count cycles due to fd
passing functionality. New method based on Tarjan's Strongly
Connected Components algorithm should be both faster and remove a
lot of workarounds we accumulated over the years.
- Add TCP fraglist GRO support, allowing chaining multiple TCP
packets and forwarding them together. Useful for small switches /
routers which lack basic checksum offload in some scenarios (e.g.
PPPoE).
- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't use
NAPI. This helps move the processing out of the softirq jumble.
- Continue work of converting from rtnl lock to RCU protection.
Don't require rtnl lock when reading: IPv6 routing FIB, IPv6
address labels, netdev threaded NAPI sysfs files, bonding driver's
sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics,
TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot
of the link information available via rtnetlink.
- Small optimizations from Eric to UDP wake up handling, memory
accounting, RPS/RFS implementation, TCP packet sizing etc.
- Allow direct page recycling in the bulk API used by XDP, for +2%
PPS.
- Support peek with an offset on TCP sockets.
- Add MPTCP APIs for querying last time packets were received/sent/acked
and whether MPTCP "upgrade" succeeded on a TCP socket.
- Add intra-node communication shortcut to improve SMC performance.
- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol
driver.
- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.
- Add reset reasons for tracing what caused a TCP reset to be sent.
- Introduce direction attribute for xfrm (IPSec) states. State can be
used either for input or output packet processing.
Things we sprinkled into general kernel code:
- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().
This required touch-ups and renaming of a few existing users.
- Add Endian-dependent __counted_by_{le,be} annotations.
- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.
Netfilter:
- Use GFP_KERNEL to clone elements, to deal better with OOM
situations and avoid failures in the .commit step.
BPF:
- Add eBPF JIT for ARCv2 CPUs.
- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function
entry and return, the entry program can decide if the return
program gets executed and the entry program can share u64 cookie
value with return program. "Session mode" is a common use-case for
tetragon and bpftrace.
- Add the ability to specify and retrieve BPF cookie for raw
tracepoint programs in order to ease migration from classic to raw
tracepoints.
- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V
JITs. This allows inlining functions which need to access per-CPU
state.
- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86
instruction. Support BPF arena on ARM64.
- Add a new bpf_wq API for deferring events and refactor
process-context bpf_timer code to keep common code where possible.
- Harden the BPF verifier's and/or/xor value tracking.
- Introduce crypto kfuncs to let BPF programs call kernel crypto
APIs.
- Support bpf_tail_call_static() helper for BPF programs with GCC 13.
- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.
Driver API:
- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by
rule.
- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line)
config.
- Initial bits of a queue control API, for now allowing a single
queue to be reset without disturbing packet flow to other queues.
- Common (ethtool) statistics for hardware timestamping.
Tests and tooling:
- Remove the need to create a config file to run the net forwarding
tests so that a naive "make run_tests" can exercise them.
- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test
machine). Add a few such tests.
- Create a shared code library for writing Python tests. Expose the
YAML Netlink library from tools/ to the tests for easy Netlink
access.
- Move netfilter tests under net/, extend them, separate performance
tests from correctness tests, and iron out issues found by running
them "on every commit".
- Refactor BPF selftests to use common network helpers.
- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF
info, TC u32 mark, TC police action.
- Teach Python YAML Netlink to decode attribute policies.
- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.
- Add hyperlinks between definitions in generated Netlink docs.
Drivers:
- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application
rather than dmesg (large number of driver changes from Asbjørn
Sloth Tønnesen).
- Ethernet high-speed NICs:
- Broadcom (bnxt):

of: property: Add fw_devlink support for interrupt-map property
Some of the PCI host controllers (such as generic PCI host controller) use "interrupt-map" DT property to describe the mapping between PCI endpoints and PCI interrupt pins. This is the only case where the interrupts are not described in DT. Currently, there is no fw_devlink created based on "interrupt-map" DT property so interrupt controller is not guaranteed to be probed before the PCI host controller. This affects every platform where both PCI host controller and interrupt controllers are probed as regular platform devices. This creates fw_devlink between consumers (PCI host controller) and supplier (interrupt controller) based on "interrupt-map" DT property.

i2c: mux: Remove class argument from i2c_mux_add_adapter()
99a741aa7a2d ("i2c: mux: gpio: remove support for class-based device
instantiation") removed the last call to i2c_mux_add_adapter() with a
non-null class argument. Therefore the class argument can be removed.
Note: Class-based device instantiation is a legacy mechanism which
shouldn't be used in new code, so we can rule out that this argument
may be needed again in the future.

of: module: add buffer overflow check in of_modalias()
In of_modalias(), if the buffer happens to be too small even for the 1st
snprintf() call, the len parameter will become negative and str parameter
(if not NULL initially) will point beyond the buffer's end. Add the buffer
overflow check after the 1st snprintf() call and fix such check after the
strlen() call (accounting for the terminating NUL char).

of: reserved_mem: Remove the use of phandle from the reserved_mem APIs
The __find_rmem() function is the only place that references the phandle field of the reserved_mem struct. __find_rmem() is used to match a device_node object to its corresponding entry in the reserved_mem array using its phandle value. But, there is already a function called of_reserved_mem_lookup() which carries out the same action using the name of the node. Using the of_reserved_mem_lookup() function is more reliable because every node is guaranteed to have a name, but not all nodes will have a phandle. Nodes are only assigned a phandle if they are explicitly defined in the DT using "phandle = <phandle_number>", or if they are referenced by another node in the DT. Hence, If the phandle field is empty, then __find_rmem() will return a false negative. Hence, delete the __find_rmem() function and switch to using the of_reserved_mem_lookup() function to find the corresponding entry of a device_node in the reserved_mem array. Since the phandle field of the reserved_mem struct is now unused, delete that as well.

STM32 Firewall bus for v6.10, round 1
Highlights: --------- Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers register to the framework to offer firewall services such as access granting. This series of patches is a new approach on the previous STM32 system bus, history is available here: https://lore.kernel.org/lkml/20230127164040.1047583/ The need for such framework arises from the fact that there are now multiple hardware firewalls implemented across multiple products. Drivers are shared between different products, using the same code. When it comes to firewalls, the purpose mostly stays the same: Protect hardware resources. But the implementation differs, and there are multiple types of firewalls: peripheral, memory, ... Some hardware firewall controllers such as the RIFSC implemented on STM32MP2x platforms may require to take ownership of a resource before being able to use it, hence the requirement for firewall services to take/release the ownership of such resources. On the other hand, hardware firewall configurations are becoming more and more complex. These mecanisms prevent platform crashes or other firewall-related incoveniences by denying access to some resources. The stm32 firewall framework offers an API that is defined in firewall controllers drivers to best fit the specificity of each firewall. For every peripherals protected by either the ETZPC or the RIFSC, the firewall framework checks the firewall controlelr registers to see if the peripheral's access is granted to the Linux kernel. If not, the peripheral is configured as secure, the node is marked populated, so that the driver is not probed for that device. The firewall framework relies on the access-controller device tree binding. It is used by peripherals to reference a domain access controller. In this case a firewall controller. The bus uses the ID referenced by the access-controller property to know where to look in the firewall to get the security configuration for the peripheral. This allows a device tree description rather than a hardcoded peripheral table in the bus driver. The STM32 ETZPC device is responsible for filtering accesses based on security level, or co-processor isolation for any resource connected to it. The RIFSC is responsible for filtering accesses based on Compartment ID / security level / privilege level for any resource connected to it. -----BEGIN PGP SIGNATURE----- iQJRBAABCgA7FiEEctl9+nxzUSUqdELdf5rJavIecIUFAmYqUUkdHGFsZXhhbmRy ZS50b3JndWVAZm9zcy5zdC5jb20ACgkQf5rJavIecIWolxAAqUHuLzXyrsCGfPG9 L5J8dUIeRk6lsQgO62EtS/hsUL5NhlwSiShtNilGw0t2TDCj0LpSMccwDjHoC1DE 9ks6aj0lO4dBl/d6fQm+4Vn85KiKfKYXW3J9w+6ZtG7pRly9jbmlrELqBIbL+MjU /mmPdKM5y/l9KO6vxiua+EtDdd0pZksZLFtms23VoiFgkQ+2heoJ297QGfrWwxzv UZg/UnWpQYB10dp93WL97vTdBZR4iUwEJNcip7xM65iBwSkuc9Y3gz0TZTO0ivZJ BRsNc/9BJYEV3kNxRJGyf7JeufsaG3meHVxw9sOYi2hMe75pDAANYxvsCYt6NHjL i+zugtcM5v//Ksw+HbD1rvRuhEWjFUotCeXJb+RaiY0Sy3HVlKG0WJm2Ybgzlbf+ vahskAHJxG0NFhPVpktQ/+gh8IU8Gy0PwyErdihhWKCiYBp8xHxW7IF7JtqlXQQS KQ4r0Ez/fgGmLQqDobskE+OgaFIuI5QrjH7S/VvxYh0xxZOBK89EmxK7pO3fki0v EFcTE/82HWfJo/bRCoq2Yzrh2omjR9ICsxDtVe4nILzjhaLChBz5lITyRO+/+Lr3 6u/oO09tlQYEK4YzH2Kw0xGtpY7Xfmm4wC+zDTRXKBM3Vp1IoTchHssLS4nZbScq ZHJHRPMCX98FdVH3BLX7OSexJys= =/Cu0 -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmYwAI4ACgkQYKtH/8kJ UicByw//VzXycIdrOzZeInbrhs0D/7pmb31U1NaAwtK3Y90lxBi5AlB4MKUrM+oq x/cxqmmW1RsBc2m1iEuJWkqXS+XJHGptHKAHUqVhI9bIuBZqmGddvcP93Ml9egcN OL/Kd/OS4Q07EYc/Md6XrRBo2zJcHT57jGH8fKBmX4eAKfPYo7xgbq5k/0LoCq/i cgfQdKeDsR6tTrHyJI0p/+EgS5uglUnIJBm1aLDk883UKH4/EQSR+dpvYsogBcbd UnH78QeUymCOYzWylHJHeWFgDnn9NiJy/oCQx7wMc6PVUhcd0l1FXvM7XUeDy7iW aNJpgYU8cTx9IYPGBbZJ13NX0+X4QACKpDjJZG90/y4Q4YEn5l/Di9rmv4HYhZgr gwYD4EHewKB3PVtmCCUQpurSblshoo9bPWEaR3NFD1mSu46Jb11/zgIQ4oBagixV MjiaaP3+Rpz1X0Zo5HSq9F0k4A/SddOo2zjMn3af/77nENsR3yEmPWgL20T+nv9P deJ/LqE6mGVFI0c4E2K03Y85wldN6xXyhvCEqlHtK2X4l5JMe+0Vnak+VICZ0jQw K/ihBRbifMH7g4GQUjpJUoUAvoyeSJ2jhMF8QV7bk76b6HeRFRYKOpQLnj29v/nd MF2rKJwFYqJDF3d2a90I3E8c7huKnqWHQWinKu2Y2NkmH/tqtcI= =mgY+ -----END PGP SIGNATURE----- Merge tag 'stm32-bus-firewall-for-v6.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32 into soc/drivers STM32 Firewall bus for v6.10, round 1 Highlights: --------- Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x platforms.

OF: Simplify DMA range calculations
Juggling start, end, and size values for a range is somewhat redundant and a little hard to follow. Consolidate down to just using inclusive start and end, which saves us worrying about size overflows for full 64-bit ranges (note that passing a potentially-overflowed value through to arch_setup_dma_ops() is benign for all current implementations, and this is working towards removing that anyway).

of: module: prevent NULL pointer dereference in vsnprintf()
In of_modalias(), we can get passed the str and len parameters which would cause a kernel oops in vsnprintf() since it only allows passing a NULL ptr when the length is also 0. Also, we need to filter out the negative values of the len parameter as these will result in a really huge buffer since snprintf() takes size_t parameter while ours is ssize_t...

of: dynamic: Synchronize of_changeset_destroy() with the devlink removals
In the following sequence:
1) of_platform_depopulate()
2) of_overlay_remove()
During the step 1, devices are destroyed and devlinks are removed.
During the step 2, OF nodes are destroyed but
__of_changeset_entry_destroy() can raise warnings related to missing
of_node_put():
ERROR: memory leak, expected refcount 1 instead of 2 ...
Indeed, during the devlink removals performed at step 1, the removal
itself releasing the device (and the attached of_node) is done by a job
queued in a workqueue and so, it is done asynchronously with respect to
function calls.
When the warning is present, of_node_put() will be called but wrongly
too late from the workqueue job.
In order to be sure that any ongoing devlink removals are done before
the of_node destruction, synchronize the of_changeset_destroy() with the
devlink removals.
Fixes:

Not a ton of stuff happening in the clk framework in this pull request. We got
some more devm helpers and we seem to be going in the direction of "just turn
this stuff on already and leave me alone!" with the addition of a
devm_clk_bulk_get_all_enable() API. I'm hoping that we can make that into a
genpd that drivers attach instead, but this API should help drivers simplify in
the meantime.
Outside of the devm wrappers, we've got the usual clk driver updates that are
dominated by the major phone SoC vendors (Samsung and Qualcomm) and the
non-critical driver fixes for things like incorrect topology descriptions and
wrong registers or bit fields. More details are below, but I'd say that it
looks pretty ordinary. The only thing that really jumps out at me is the
Renesas clk driver that's ignoring clks that are assigned to remote processors
in DeviceTree. That's a new feature that they're using to avoid marking clks as
CLK_IGNORE_UNUSED based on the configuration of the system.
Core:
- Increase dev_id len for clkdev lookups
- Add a devm_clk_bulk_get_all_enable() API to get and enable all clks
for a device
- Add a devm variant of clk_rate_exclusive_get()
New Drivers:
- Display, TCSR, GPU, and Camera clock controllers for Qualcomm's X1 Elite SoC
- Google GS101 PERIC0 and PERIC1 clock controllers
- Exynos850 PDMA clocks
- Exynos850 CPU cluster 0 and 1 (CMU_CPUCLK0/CMU_CPUCLK1) clock controllers
Removed Drivers:
- Remove the unused Qualcomm sc7180 modem clk driver
Updates:
- Fix some static checker errors in the Hisilicon clk driver
- Polarfire MSSPLL hardware has 4 output clocks (the driver supported
previously only one output); each of these 4 outputs feed dividers and the
output of each divider feed individual hardware blocks (e.g. CAN, Crypto,
eMMC); individual hardware block drivers need to control their clocks thus
clock driver support was added for all MSSPLL output clocks
- Typo fixes in the Qualcomm IPQ5018 GCC driver
- Add "qdss_at" clk on Qualcomm IPQ6018, needed for WiFi
- Properly terminate frequency tables in different Qualcomm clk drivers
- Add MDSS, crypto, and SDCC resets on Qualcomm MSM8953
- Add missing UFS CLKREF clks on Qualcomm SC8180X
- Avoid significant delays during boot by adding a softdep on rpmhpd to
Qualcomm SDM845 gcc driver
- Add QUPv3 RCGS w/ DFS and video resets to Qualcomm SM8150 GCC driver
- Fix the custom GPU GX "do-nothing" method in the Qualcomm GDSC driver
- Add an external regulator to GX GDSC on Qualcomm SC8280XP GPU clk driver
- Switch display, GPU, video, and camera Qualcomm clk drivers to
module_platform_driver()
- Set a longer delay for Venus resets on many Qualcomm SoCs
- Correct the GDSC wait times in the Qualcomm SDM845 display clk driver
- Fix clock listing Oops on Amlogic axg
- New pll-rate for Rockchip rk3568
- i2s rate improvements for Rockchip rk3399
- Rockchip rk3588 syscon clock fixes and removal of overall clock-number from
the rk3588 binding header
- A prerequisite for later improvements to the Rockchip rk3588 linked clocks
- Minor clean-ups and error handling improvements in both composite-8m and SCU
i.MX clock drivers
- Fix for SAI_MCLK_SEL definition for i.MX8MP
- Register the Samsung CMU MISC clock controller earlier, so the Multi Core
Timer clocksource can use it on Google GS101
- Propagate Exynos850 SPI IPCLK rate change to parents, so the SPI will get
proper clock rates
- Refactor the generic Samsung CPU clock controllers code, preparing it for
supporting Exynos850 CPU clocks
- Fix some clk kerneldoc warnings
- Add Ethernet, SDHI, DMA, and HyperFLASH/QSPI (RPC-IF) clocks on Renesas
R-Car V4M
- Ignore all clocks which are assigned to a non-Linux system in the Renesas
clk driver
- Add watchdog clock on Renesas RZ/G3S
- Add camera (CRU) clock and reset on Renesas RZ/G2UL
- Add support for the Renesas R-Car V4M (R8A779H0) SoC
- Convert some clk bindings to YAML so they can be validated

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"Not a ton of stuff happening in the clk framework. We got some more
devm helpers and we seem to be going in the direction of "just turn
this stuff on already and leave me alone!" with the addition of a
devm_clk_bulk_get_all_enable() API. I'm hoping that we can make that
into a pmdomain that drivers attach instead, but this API should help
drivers simplify in the meantime.
Outside of the devm wrappers, we've got the usual clk driver updates
that are dominated by the major phone SoC vendors (Samsung and
Qualcomm) and the non-critical driver fixes for things like incorrect
topology descriptions and wrong registers or bit fields. More details
are below, but I'd say that it looks pretty ordinary. The only thing
that really jumps out at me is the Renesas clk driver that's ignoring
clks that are assigned to remote processors in DeviceTree. That's a
new feature that they're using to avoid marking clks as
CLK_IGNORE_UNUSED based on the configuration of the system.
Core:
- Increase dev_id len for clkdev lookups
- Add a devm_clk_bulk_get_all_enable() API to get and enable all clks
for a device
- Add a devm variant of clk_rate_exclusive_get()
New Drivers:
- Display, TCSR, GPU, and Camera clock controllers for Qualcomm's X1
Elite SoC
- Google GS101 PERIC0 and PERIC1 clock controllers
- Exynos850 PDMA clocks
- Exynos850 CPU cluster 0 and 1 (CMU_CPUCLK0/CMU_CPUCLK1) clock
controllers
Removed Drivers:
- Remove the unused Qualcomm sc7180 modem clk driver
Updates:
- Fix some static checker errors in the Hisilicon clk driver
- Polarfire MSSPLL hardware has 4 output clocks (the driver supported
previously only one output); each of these 4 outputs feed dividers
and the output of each divider feed individual hardware blocks
(e.g. CAN, Crypto, eMMC); individual hardware block drivers need to
control their clocks thus clock driver support was added for all
MSSPLL output clocks
- Typo fixes in the Qualcomm IPQ5018 GCC driver
- Add "qdss_at" clk on Qualcomm IPQ6018, needed for WiFi
- Properly terminate frequency tables in different Qualcomm clk
drivers
- Add MDSS, crypto, and SDCC resets on Qualcomm MSM8953
- Add missing UFS CLKREF clks on Qualcomm SC8180X
- Avoid significant delays during boot by adding a softdep on rpmhpd
to Qualcomm SDM845 gcc driver
- Add QUPv3 RCGS w/ DFS and video resets to Qualcomm SM8150 GCC
driver
- Fix the custom GPU GX "do-nothing" method in the Qualcomm GDSC
driver
- Add an external regulator to GX GDSC on Qualcomm SC8280XP GPU clk
driver
- Switch display, GPU, video, and camera Qualcomm clk drivers to
module_platform_driver()
- Set a longer delay for Venus resets on many Qualcomm SoCs
- Correct the GDSC wait times in the Qualcomm SDM845 display clk
driver
- Fix clock listing Oops on Amlogic axg
- New pll-rate for Rockchip rk3568
- i2s rate improvements for Rockchip rk3399
- Rockchip rk3588 syscon clock fixes and removal of overall
clock-number from the rk3588 binding header
- A prerequisite for later improvements to the Rockchip rk3588 linked
clocks
- Minor clean-ups and error handling improvements in both
composite-8m and SCU i.MX clock drivers
- Fix for SAI_MCLK_SEL definition for i.MX8MP
- Register the Samsung CMU MISC clock controller earlier, so the
Multi Core Timer clocksource can use it on Google GS101
- Propagate Exynos850 SPI IPCLK rate change to parents, so the SPI
will get proper clock rates
- Refactor the generic Samsung CPU clock controllers code, preparing
it for supporting Exynos850 CPU clocks
- Fix some clk kerneldoc warnings
- Add Ethernet, SDHI, DMA, and HyperFLASH/QSPI (RPC-IF) clocks on
Renesas R-Car V4M
- Ignore all clocks which are assigned to a non-Linux system in the
Renesas clk driver
- Add watchdog clock on Renesas RZ/G3S
- Add camera (CRU) clock and reset on Renesas RZ/G2UL
- Add support for the Renesas R-Car V4M (R8A779H0) SoC
- Convert some clk bindings to YAML so they can be validated"

from hotplugged memory rather than only from main memory. Series
"implement "memmap on memory" feature on s390".
- More folio conversions from Matthew Wilcox in the series
"Convert memcontrol charge moving to use folios"
"mm: convert mm counter to take a folio"
- Chengming Zhou has optimized zswap's rbtree locking, providing
significant reductions in system time and modest but measurable
reductions in overall runtimes. The series is "mm/zswap: optimize the
scalability of zswap rb-tree".
- Chengming Zhou has also provided the series "mm/zswap: optimize zswap
lru list" which provides measurable runtime benefits in some
swap-intensive situations.
- And Chengming Zhou further optimizes zswap in the series "mm/zswap:
optimize for dynamic zswap_pools". Measured improvements are modest.
- zswap cleanups and simplifications from Yosry Ahmed in the series "mm:
zswap: simplify zswap_swapoff()".
- In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
contributed several DAX cleanups as well as adding a sysfs tunable to
control the memmap_on_memory setting when the dax device is hotplugged
as system memory.
- Johannes Weiner has added the large series "mm: zswap: cleanups",
which does that.
- More DAMON work from SeongJae Park in the series
"mm/damon: make DAMON debugfs interface deprecation unignorable"
"selftests/damon: add more tests for core functionalities and corner cases"
"Docs/mm/damon: misc readability improvements"
"mm/damon: let DAMOS feeds and tame/auto-tune itself"
- In the series "mm/mempolicy: weighted interleave mempolicy and sysfs
extension" Rakie Kim has developed a new mempolicy interleaving policy
wherein we allocate memory across nodes in a weighted fashion rather
than uniformly. This is beneficial in heterogeneous memory environments
appearing with CXL.

- Muhammad Usama Anjum has reworked the selftest code to make its
human-readable output conform to the TAP ("Test Anything Protocol")
format. Amongst other things, this opens up the use of third-party
tools to parse and process out selftesting results.
- Ryan Roberts has added fork()-time PTE batching of THP ptes in the
series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
targeted at arm64, this significantly speeds up fork() when the process
has a large number of pte-mapped folios.
- David Hildenbrand also gets in on the THP pte batching game in his
series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
implements batching during munmap() and other pte teardown situations.
The microbenchmark improvements are nice.
- And in the series "Transparent Contiguous PTEs for User Mappings" Ryan
Roberts further utilizes arm's pte's contiguous bit ("contpte
mappings"). Kernel build times on arm64 improved nicely. Ryan's series
"Address some contpte nits" provides some followup work.

Mark Brown did what the title claims.
- Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring".
- Even more zswap material from Nhat Pham. The series "fix and extend
zswap kselftests" does as claimed.
- In the series "Introduce cpu_dcache_is_aliasing() to fix DAX
regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in
our handling of DAX on archiecctures which have virtually aliasing data
caches. The arm architecture is the main beneficiary.

improvements in worst-case mmap_lock hold times during certain
userfaultfd operations.
- Some page_owner enhancements and maintenance work from Oscar Salvador
in his series
"page_owner: print stacks and their outstanding allocations"
"page_owner: Fixup and cleanup"
- Uladzislau Rezki has contributed some vmalloc scalability improvements
in his series "Mitigate a vmap lock contention". It realizes a 12x
improvement for a certain microbenchmark.
- Some kexec/crash cleanup work from Baoquan He in the series "Split
crash out from kexec and clean up related config items".
- Some zsmalloc maintenance work from Chengming Zhou in the series
"mm/zsmalloc: fix and optimize objects/page migration"
"mm/zsmalloc: some cleanup for get/set_zspage_mapping()"
- Zi Yan has taught the MM to perform compaction on folios larger than
order=0. This a step along the path to implementaton of the merging of
large anonymous folios. The series is named "Enable >0 order folio
memory compaction".
- Christoph Hellwig has done quite a lot of cleanup work in the
pagecache writeback code in his series "convert write_cache_pages() to
an iterator".
- Some modest hugetlb cleanups and speedups in Vishal Moola's series
"Handle hugetlb faults under the VMA lock".
- Zi Yan has changed the page splitting code so we can split huge pages
into sizes other than order-0 to better utilize large folios. The
series is named "Split a folio to any lower order folios".
- David Hildenbrand has contributed the series "mm: remove
total_mapcount()", a cleanup.
- Matthew Wilcox has sought to improve the performance of bulk memory
freeing in his series "Rearrange batched folio freeing".
- Gang Li's series "hugetlb: parallelize hugetlb page init on boot"
provides large improvements in bootup times on large machines which are
configured to use large numbers of hugetlb pages.
- Matthew Wilcox's series "PageFlags cleanups" does that.
- Qi Zheng's series "minor fixes and supplement for ptdesc" does that
also. S390 is affected.
- Cleanups to our pagemap utility functions from Peter Xu in his series
"mm/treewide: Replace pXd_large() with pXd_leaf()".
- Nico Pache has fixed a few things with our hugepage selftests in his
series "selftests/mm: Improve Hugepage Test Handling in MM Selftests".

of: Create of_root if no dtb provided by firmware
When enabling CONFIG_OF on a platform where 'of_root' is not populated by firmware, we end up without a root node. In order to apply overlays and create subnodes of the root node, we need one. Create this root node by unflattening an empty builtin dtb. If firmware provides a flattened device tree (FDT) then the FDT is unflattened via setup_arch(). Otherwise, the call to unflatten(_and_copy)?_device_tree() will create an empty root node. We make of_have_populated_dt() return true only if the DTB was loaded by firmware so that existing callers don't change behavior after this patch. The call in the of platform code is removed because it prevents overlays from creating platform devices when the empty root node is used.

of: Always unflatten in unflatten_and_copy_device_tree()
We want to populate an empty DT whenever CONFIG_OF is enabled so that overlays can be applied and the DT unit tests can be run. Make unflatten_and_copy_device_tree() stop printing a warning if the 'initial_boot_params' pointer is NULL. Instead, simply copy the dtb if there is one and then unflatten it. If there isn't a DT to copy, then the call to unflatten_device_tree() is largely a no-op, so nothing really changes here.

of: Reimplement of_machine_is_compatible() using of_machine_compatible_match()
of_machine_compatible_match() works with a table of strings. of_machine_is_compatible() is a simplier version with only one string.

of: Change of_machine_is_compatible() to return bool
of_machine_is_compatible() currently returns a positive integer if it finds a match. However none of the callers ever check the value, they all treat it as a true/false. So change of_machine_is_compatible() to return bool, which will allow the implementation to be changed in a subsequent patch.

of: Add of_machine_compatible_match()
We have of_machine_is_compatible() to check if a machine is compatible with a single compatible string. However some code is able to support multiple compatible boards, and so wants to check for one of many compatible strings. So add of_machine_compatible_match() which takes a NULL terminated array of compatible strings to check against the root node's compatible property. Compared to an open coded match this is slightly more self documenting, and also avoids the caller needing to juggle the root node either directly or via of_find_node_by_path().

of/platform: Inform about created platform devices using pr_debug()
For most nodes with a compatible property a platform device is created. For some an amba device is created instead. For the latter of_amba_device_create() emits a message at debug level about the node the device is created from. Add a similar message to of_platform_device_create_pdata() to inform about the whole list of created devices. This also gives the right context for the following messages that inform about created child devices.

IIO: 1st set of new device support, features and cleanup for 6.9
IIO Backend support =================== New approach from Nuno Sa to the problem of reuse of drivers with IIO devices that are actually the combination of a highspeed chip and an FPGA core handling the data capture and flows. It will hopefully also apply to some other split designs. The ad9467 and axi-adi drivers are converted over to this framework. New device support ================== adi,admfm2000 - New driver for this dual microwave down converter. ams,as73211 - Add support for as7331 UV sensor. richtek,rtq6056 - Add support for related parts RTQ6053 and RTQ6059 st,lsm6dsx - Add ASM330LHHXG1 accelerometer and gyro support (mainly IDs) ti,ads1298 - New driver for this medical ADC. Features ======== tests - Unit tests for the gain-time-scale helper library. bosch,bmi088 - I2C support. bosh,bmi160 - Add 10EC5280 ACPI ID. Used in a number of devices that won't get fixed. The ID is actually a PCI ID belonging to realtech. No response was received to earlier attempts to notify them of this. The manufacturers of some devices have replied to say they will not fix this incorrect ID. Add the ID and hope it isn't a problem. bosch,bmi323 - Add BOSC0200 ACPI ID. Note this is a duplicate of one in the bmc150 driver (it appears these parts share a windows driver). Both drivers perform an ID check that is safe on the other part before successfully probing. hid-sensors-als - Add color temperature and chromaticity support. Note this is a replacement for the series reverted in 6.8 that correctly handles all the potential channel combinations. honeywell,hsc030pa - Triggered buffer support (after driver cleanup). honeywell,mprls00025pa - Improved error handling. - New DT binding to allow use of part number triplet as provided in data sheet to specify equivalent of most of the binding more efficiently. - SPI support. memsic,mxc4005 - ACPI ID MDA6655 as seen in the Chuwi Minibook X 2023 ti,hdc3020 - Add threshold event support (after some driver cleanup) veml,vcnl4000 - Switch to high resolution proximity measurement. Cleanup ======= Various minor typo fixes and better use of defines etc. Treewide - Stop using ACPI_PTR(). The savings in space are small and not worth the complexity of __maybe_unused of ifdef guards. To avoid use in new IIO drivers based on copy and paste, clean it out. - cleanup.h based handling of iio_device_claim_direct_mode()/ iio_device_release_direct_mode() using scope_cond_guard(). In many drivers this is combined with other automated cleanup to give maximum simplifications. An initial set of drivers are converted over to this infrastructure. Tools - Use rewinddir() instead of seekdir() to return to start of file. core - Make iio_bus_type constant. adi,ad16475 - Use irq_get_trigger_type() instead of opencoding. adi,ad16480 - Use irq_get_trigger_type() instead of opencoding. adi,ad-sigma-delta - Avoid overwriting IRQ flags if provided by firmware. ams,as73211 - Use IIO_VAL_FRACTIONAL for scales to simplify the code and potentially improve accuracy. gts-library - Use a div64_u64() instead of a loop to do a division. honeywell,mprls00025pa - Clean up dt-binding doc. - Drop defaults when DT binding not providing values. Very unlikely these were useful given they were wrong for vast majority of supported devices. - Whitespace cleanup miramems,da280 - Use i2c_get_match_data() to replace hand rolled ACPI matching code. semtech,sx9324 - Avoid unnecessary copying of property strings. st,lsm6dsx - Improve docs, particularly wrt to making addition of new device support less noisy. st,lsm9ds0 - Use dev_err_probe() in all probe() error handling. - Improved header includes. - Tidy up termination of ID tables. ti,ads1014 - Correct upper bound on PGA (wrong value had no actual impact) ti,afe4403/4404 - devm_ useage to simplify error handling in probe() and allow() remove to be dropped. voltage-divider - Add dt-binding for io-channel-cells to allow such a device to be both an IIO consumer and IIO producer at the same time. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEbilms4eEBlKRJoGxVIU0mcT0FogFAmXXmXERHGppYzIzQGtl cm5lbC5vcmcACgkQVIU0mcT0Foj8Bg/+OZgU0FOEhUXidF58ulMBPTmWG4qBsCCK nB8MhimNn9XcoUDkZwns5ABgRKJvYVqK3VXaGj7HXRcpHzjOAHDCD1aS9EDdwHuo prH9Q5L7iVMhOjKcK3UwtzbUOAjrrmE4Oa74RH4oDLKV9ws6mb1VQfoOgpRNTsTK rA0A3B4W78U+UxLZPWIuYDUS/BgDfSfB024VFtUhMvo0B6G52u6hoDk04//hQuW8 IE0db4VxJLuRDYinBiTbtFtXWO8FNWd8r37MlQKx/llEKtjzI1ZttOK8DyQRudJ7 rLP3nO8svCcQ9oJn0YrnFL9y6PlW/ASUaXH47xBfAiCdKgHlQTf3kDyzwddCqQRD 3cqghbUbYp65Nm1o2TXYQio4zEInS/1ZMzpezb9K1+oiz/xGarjMCR+J4Za4cw76 5jCfnp8vBPDX7JdGwYgbK9nXkXAJ5ewdm7ad03t3oPwfAQPlXfAHIWDT8evNDVlc L94RSmKeMKL1BG3jOr7mJbqIwivf799pgudVJMuBfnlYR+gkBBVvFWhXrgvsJWhQ gKhqfEYCjtJ/t483zcJporvWBmmmf6gUvNOB4x6oA0j85GPGoDlTdfK54dkD+98k KP83Wd4LqDOM6V6PE+L7yTW05sOgT2qDHYrw/qAPoEogThSSCoqRm/kWwPBv3toL 0ykQId5/UBk= =xkgf -----END PGP SIGNATURE----- Merge tag 'iio-for-6.9a' of http://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO: 1st set of new device support, features and cleanup for 6.9 IIO Backend support =================== New approach from Nuno Sa to the problem of reuse of drivers with IIO devices that are actually the combination of a highspeed chip and an FPGA core handling the data capture and flows.

of: Fix double free in of_parse_phandle_with_args_map
In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.
Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".
Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.

of/platform: Disable sysfb if a simple-framebuffer node is found
Some DT platforms use EFI to boot and in this case the EFI Boot Services
may register a EFI_GRAPHICS_OUTPUT_PROTOCOL handle, that will later be
queried by the Linux EFI stub to fill the global struct screen_info data.
The data is used by the Generic System Framebuffers (sysfb) framework to
add a platform device with platform data about the system framebuffer.
But if there is a "simple-framebuffer" node in the DT, the OF core will
also do the same and add another device for the system framebuffer.
This could lead for example, to two platform devices ("simple-framebuffer"
and "efi-framebuffer") to be added and matched with their corresponding
drivers. So both efifb and simpledrm will be probed, leading to following:
[ 0.055752] efifb: framebuffer at 0xbd58dc000, using 16000k, total 16000k
[ 0.055755] efifb: mode is 2560x1600x32, linelength=10240, pages=1
[ 0.055758] efifb: scrolling: redraw
[ 0.055759] efifb: Truecolor: size=2:10:10:10, shift=30:20:10:0
...
[ 3.295896] simple-framebuffer bd58dc000.framebuffer: [drm] *ERROR*
could not acquire memory range [??? 0xffff79f30a29ee40-0x2a5000001a7
flags 0x0]: -16
[ 3.298018] simple-framebuffer: probe of bd58dc000.framebuffer
failed with error -16
To prevent the issue, make the OF core to disable sysfb if there is a node
with a "simple-framebuffer" compatible. That way only this device will be
registered and sysfb would not attempt to register another one using the
screen_info data even if this has been filled.
This seems the correct thing to do in this case because:
a) On a DT platform, the DTB is the single source of truth since is what
describes the hardware topology. Even if EFI Boot Services are used to
boot the machine.
b) The of_platform_default_populate_init() function is called in the
arch_initcall_sync() initcall level while the sysfb_init() function
is called later in the subsys_initcall() initcall level.

of: address: Consolidate bus .map() functions
The bus .map() functions vary only by checking the flag cells values and skipping over any flag cells to read the addresses. Otherwise they all do the same reading 'ranges' address and size and returning the address's offset if it is within the 'ranges' entry. Refactor all the .map() functions to pass in the flag cell size so that each bus can check the bus specific flags and then call a common function to do everything else.

amba: bus: balance firmware node reference counting
Currently the ACPI code doesn't bump the reference count of the firmware node, while OF counter part does. Not that it's a problem right now, since ACPI doesn't really use the reference counting for firmware nodes, it still makes sense to make code robust against any changes done there. For this, - switch ACPI case to use device_set_node() to be unified with OF - move reference counting to amba_device_add() - switch to use firmware nodes instead of OF ones In the result we will have reference counting done in the same module for all callers independently on the nature of firmware node behind.

Devicetree updates for v6.6:
DT core:
- Add support for generating DT nodes for PCI devices. This is the
groundwork for applying overlays to PCI devices containing
non-discoverable downstream devices.
- DT unittest additions to check reverted changesets, to test for
refcount issues, and to test unresolved symbols. Also, various
clean-ups of the unittest along the way.
- Refactor node and property manipulation functions to better share code
with old API and changeset API
- Refactor changeset print functions to a common implementation
- Move some platform_device specific functions into of_platform.c
Bindings:
- Treewide fixing of typos
- Treewide clean-up of SPDX tags to use 'OR' consistently
- Last chunk of dropping unnecessary quotes. With that, the check
for unnecessary quotes is enabled in yamllint.
- Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
bindings to DT schema format
- Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450 Inline
Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt controller,
Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings
- Fixes for Rockchip DWC PCI binding
- Ensure all properties are evaluated on USB connector schema
- Fix dt-check-compatible script to find of_device_id instances with
compiler annotations

of: unittest: Fix of_unittest_pci_node() kconfig dependencies
of_unittest_pci_node test depends on both CONFIG_PCI_DYNAMIC_OF_NODES
and CONFIG_OF_OVERLAY. Move the test into the existing
CONFIG_OF_OVERLAY ifdef and rework the CONFIG_PCI_DYNAMIC_OF_NODES
dependency to use IS_ENABLED() instead. This reduces the combinations to
build.

of: unittest: Cleanup partially-applied overlays
When of_overlay_fdt_apply() fails, the changeset may be partially applied, and the caller is still expected to call of_overlay_remove() to clean up this partial state. However, overlay_17 is the only test that takes care of cleaning up after an (expected) failure. Instead of adding cleanup code to each individual test, extend overlay_info with the optional expected return value of of_overlay_remove(), and handle cleanup in the overlay_data_apply() helper. While at it, simplify the end marker in the overlay_info table. Update the expected error output for errors during the newly cleanup.

of: overlay: Call of_changeset_init() early
When of_overlay_fdt_apply() fails, the changeset may be partially
applied, and the caller is still expected to call of_overlay_remove() to
clean up this partial state.
However, of_overlay_apply() calls of_resolve_phandles() before
init_overlay_changeset(). Hence if the overlay fails to apply due to an
unresolved symbol, the overlay_changeset.cset.entries list is still
uninitialized, and cleanup will crash with a NULL-pointer dereference in
overlay_removal_is_ok().
Fix this by moving the call to of_changeset_init() from
init_overlay_changeset() to of_overlay_fdt_apply(), where all other
early initialization is done.

of: overlay: Extend of_overlay_fdt_apply() to specify the target node
Currently, in an overlay fdt fragment, it needs to specify the exact
location in base DT. In another word, when the fdt fragment is generated,
the base DT location for the fragment is already known.
There is new use case that the base DT location is unknown when fdt
fragment is generated. For example, the add-on device provide a fdt
overlay with its firmware to describe its downstream devices. Because it
is add-on device which can be plugged to different systems, its firmware
will not be able to know the overlay location in base DT. Instead, the
device driver will load the overlay fdt and apply it to base DT at runtime.
In this case, of_overlay_fdt_apply() needs to be extended to specify
the target node for device driver to apply overlay fdt.
int overlay_fdt_apply(..., struct device_node *base);

of: dynamic: Fix race in getting old property when updating property
__of_update_property() returns the existing property if there is one, but that value is never added to the changeset. Updates work because the existing property was also retrieved before in of_changeset_action(), but that is racy as of_changeset_action() doesn't hold any locks. The property could be changed before the changeset is applied.

of: dynamic: Refactor changeset action printing to common helpers
Several places print the changeset action with node and property details. Refactor these into a common printing helper. The complicating factor is some prints are debug and some are errors. Solve this with a bit of preprocessor magic. Some cases printed the 'cset' which was the changeset entry pointer rather than the whole changeset itself. The changeset entry is not all that interesting and gets obfuscated by default anyways. So just drop it.

of: dynamic: Refactor action prints to not use "%pOF" inside devtree_lock
While originally it was fine to format strings using "%pOF" while
holding devtree_lock, this now causes a deadlock. Lockdep reports:
of_get_parent from of_fwnode_get_parent+0x18/0x24
^^^^^^^^^^^^^
of_fwnode_get_parent from fwnode_count_parents+0xc/0x28
fwnode_count_parents from fwnode_full_name_string+0x18/0xac
fwnode_full_name_string from device_node_string+0x1a0/0x404
device_node_string from pointer+0x3c0/0x534
pointer from vsnprintf+0x248/0x36c
vsnprintf from vprintk_store+0x130/0x3b4
Fix this by moving the printing in __of_changeset_entry_apply() outside
the lock. As the only difference in the multiple prints is the action
name, use the existing "action_names" to refactor the prints into a
single print.

mm,ima,kexec,of: use memblock_free_late from ima_free_kexec_buffer
The code calling ima_free_kexec_buffer runs long after the memblock
allocator has already been torn down, potentially resulting in a use
after free in memblock_isolate_range.
With KASAN or KFENCE, this use after free will result in a BUG
from the idle task, and a subsequent kernel panic.
Switch ima_free_kexec_buffer over to memblock_free_late to avoid
that issue.

of: module: Export of_device_uevent()
The content of of_device_uevent() is currently hardcoded in a driver that can be compiled as a module. Nothing prevents of_device_uevent() to be exported to modules, most of the other helpers in of/device.c actually are. The reason why this helper was not exported is because it has been so far only useful in drivers/base, which is built-in anyway. With the idea of getting rid of the hardcoded implementation of of_device_uevent() in other places in the kernel, let's export it to GPL modules (very much like its cousins in the same file).

of: reserved_mem: Use stable allocation order
sort() in Linux is based on heapsort which is not a stable sort algorithm - equal elements are being reordered. For reserved memory in the device tree this happens mainly for dynamic allocations: They do not have an address to sort with, so they are reordered somewhat randomly when adding/removing other unrelated reserved memory nodes. Functionally this is not a big problem, but it's confusing during development when all the addresses change after adding unrelated reserved memory nodes. Make the order stable by sorting dynamic allocations according to the node order in the device tree. Static allocations are not affected by this because they are still sorted by their (fixed) address.

of: reserved_mem: Try to keep range allocations contiguous
Right now dynamic reserved memory regions are allocated either
bottom-up or top-down, depending on the memblock setting of the
architecture. This is fine when the address is arbitrary. However,
when using "alloc-ranges" the regions are often placed somewhere
in the middle of (free) RAM, even if the range starts or ends next
to another (static) reservation.
Try to detect this situation, and choose explicitly between bottom-up
or top-down to allocate the memory close to the other reservations:
1. If the "alloc-range" starts at the end or inside an existing
reservation, use bottom-up.
2. If the "alloc-range" ends at the start or inside an existing
reservation, use top-down.
3. If both or none is the case, keep the current
(architecture-specific) behavior.
There are plenty of edge cases where only a more complex algorithm
would help, but even this simple approach helps in many cases to keep
the reserved memory (and therefore also the free memory) contiguous.

of: fdt: Scan /memreserve/ last
Change the scanning /memreserve/ and /reserved-memory node order to fix Kernel panic on Khadas Vim3 Board. If /memreserve/ goes first, the memory is reserved, but nomap can't be applied to the region. So the memory won't be used by Linux, but it is still present in the linear map as normal memory, which allows speculation. Legitimate access to adjacent pages will cause the CPU to end up prefetching into them leading to Kernel panic. So /reserved-memory node should go first, as it has a more updated description of the memory regions and can apply flags, like nomap.

riscv: Use PUD/P4D/PGD pages for the linear mapping
During the early page table creation, we used to set the mapping for PAGE_OFFSET to the kernel load address: but the kernel load address is always offseted by PMD_SIZE which makes it impossible to use PUD/P4D/PGD pages as this physical address is not aligned on PUD/P4D/PGD size (whereas PAGE_OFFSET is). But actually we don't have to establish this mapping (ie set va_pa_offset) that early in the boot process because: - first, setup_vm installs a temporary kernel mapping and among other things, discovers the system memory, - then, setup_vm_final creates the final kernel mapping and takes advantage of the discovered system memory to create the linear mapping. During the first phase, we don't know the start of the system memory and then until the second phase is finished, we can't use the linear mapping at all and phys_to_virt/virt_to_phys translations must not be used because it would result in a different translation from the 'real' one once the final mapping is installed. So here we simply delay the initialization of va_pa_offset to after the system memory discovery. But to make sure noone uses the linear mapping before, we add some guard in the DEBUG_VIRTUAL config. Finally we can use PUD/P4D/PGD hugepages when possible, which will result in a better TLB utilization. Note that: - this does not apply to rv32 as the kernel mapping lies in the linear mapping. - we rely on the firmware to protect itself using PMP.

of/address: Add of_property_read_reg() helper

treewide: Fix probing of devices in DT overlays
When loading a DT overlay that creates a device, the device is not
probed, unless the DT overlay is unloaded and reloaded again.
After the recent refactoring to improve fw_devlink, it no longer depends
on the "compatible" property to identify which device tree nodes will
become struct devices. fw_devlink now picks up dangling consumers
(consumers pointing to descendent device tree nodes of a device that
aren't converted to child devices) when a device is successfully bound
to a driver. See __fw_devlink_pickup_dangling_consumers().
However, during DT overlay, a device's device tree node can have
sub-nodes added/removed without unbinding/rebinding the driver. This
difference in behavior between the normal device instantiation and
probing flow vs. the DT overlay flow has a bunch of implications that
are pointed out elsewhere[1]. One of them is that the fw_devlink logic
to pick up dangling consumers is never exercised.
This patch solves the fw_devlink issue by marking all DT nodes added by
DT overlays with FWNODE_FLAG_NOT_DEVICE (fwnode that won't become
device), and by clearing the flag when a struct device is actually
created for the DT node. This way, fw_devlink knows not to have
consumers waiting on these newly added DT nodes, and to propagate the
dependency to an ancestor DT node that has the corresponding struct
device.
Based on a patch by Saravana Kannan, which covered only platform and spi
devices.

This helper does not produce a real modalias, but tries to get the "product" compatible part of the "vendor,product" compatibles only. It is far from creating a purely useful modalias string and does not seem to be used like that directly anyway, so let's try to give this helper a more meaningful name before moving there a real modalias helper (already existing under of/device.c).

of: Fix modalias string generation
The helper generating an OF based modalias (of_device_get_modalias())
works fine, but due to the use of snprintf() internally it needs a
buffer one byte longer than what should be needed just for the entire
string (excluding the '\0'). Most users of this helper are sysfs hooks
providing the modalias string to users. They all provide a PAGE_SIZE
buffer which is way above the number of bytes required to fit the
modalias string and hence do not suffer from this issue.
There is another user though, of_device_request_module(), which is only
called by drivers/usb/common/ulpi.c. This request module function is
faulty, but maybe because in most cases there is an alternative, ULPI
driver users have not noticed it.
In this function, of_device_get_modalias() is called twice. The first
time without buffer just to get the number of bytes required by the
modalias string (excluding the null byte), and a second time, after
buffer allocation, to fill the buffer. The allocation asks for an
additional byte, in order to store the trailing '\0'. However, the
buffer *length* provided to of_device_get_modalias() excludes this extra
byte. The internal use of snprintf() with a length that is exactly the
number of bytes to be written has the effect of using the last available
byte to store a '\0', which then smashes the last character of the
modalias string.
Provide the actual size of the buffer to of_device_get_modalias() to fix
this issue.
Note: the "str[size - 1] = '\0';" line is not really needed as snprintf
will anyway end the string with a null byte, but there is a possibility
that this function might be called on a struct device_node without
compatible, in this case snprintf() would not be executed. So we keep it
just to avoid possible unbounded strings.

of: unittest: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

blocking and atomic variants so far, but that was problematic
as this approach does not scale with required new variants
which just differ in the GFP flags used.
So Jason consolidated this back into single functions that
take a GFP parameter. This has the potential to cause
conflicts with other trees, as they introduce new call-sites
for the changed functions. I offered them to pull in the
branch containing these changes and resolve it, but I am not
sure everyone did that. The conflicts this caused with
upstream up to v6.2-rc8 are resolved in the final merge
commit.

Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work falls
into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be moved
into read-only memory (i.e. const) The recent work with Rust has
pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only making
things safer overall. This is the contuation of that work (started
last release with kobject changes) in moving struct bus_type to be
constant. We didn't quite make it for this release, but the
remaining patches will be finished up for the release after this
one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems.

Char/Misc and other driver subsystem changes for 6.3-rc1
Here is the large set of driver changes for char/misc drivers and other
smaller driver subsystems that flow through this git tree.
Included in here are:
- New IIO drivers and features and improvments in that subsystem
- New hwtracing drivers and additions to that subsystem
- lots of interconnect changes and new drivers as that subsystem seems
under very active development recently. This required also merging
in the icc subsystem changes through this tree.
- FPGA driver updates
- counter subsystem and driver updates
- MHI driver updates
- nvmem driver updates
- documentation updates
- Other smaller driver updates and fixes, full details in the shortlog
All of these have been in linux-next for a while with no reported
