We are using a wrong mcbsp functional clock. The interconnect target module
driver provided clock for mcbsp is not same as the mcbsp functional clock
known as the gfclk main_clk. The mcbsp functional clocks for mcbsp should
have been added before we dropped the legacy platform data.
Additionally we are also missing the clock aliases for the clocks used by
the audio driver if reparenting is needed. This causes audio driver errors
like "CLKS: could not clk_get() prcm_fck" for mcbsp as reported by Andreas.
The mcbsp clock aliases too should have been added before we dropped the
legacy platform data.
Let's add the clocks and aliases with a single patch to fix the issue.

Regulator drivers were modified to use asynchronous device probe. Since
then, the board .init_late hook fails to acquire a GPIO based fixed
regulator needed by an on-board voice MODEM device, and unregisters the
MODEM. That in turn triggers a so far not discovered bug of device
unregister function called for a device with no associated release() op.

The regulator hangs of a GPIO pin controlled by basic-mmio-gpio driver.
Unlike most GPIO drivers, that driver doesn't probe for devices before
device_initcall, then GPIO pins under its control are not availabele to
majority of devices probed at that phase, including regulators. On the
other hand, serial8250 driver used by the MODEM device neither accepts via
platform data nor handles regulators, then the board file is not able to
teach that driver to return -EPROBE_DEFER when the regulator is not ready
so the failed probe is retried after late_initcall.
Resolve the issue by extending description of the MODEM device with a
dedicated power management domain. Acquire the regulator from the
domain's .activate hook and return -EPROBE_DEFER if the regulator is not
available. Having that under control, add the regulator device
description to the list of platform devices initialized from .init_machine
and drop the no longer needed custom .init_late hook.

Fixes for v6.6-rc5
- fix to not reset the PHY everytime we start link training but only
do it if link training fails. Without this, the PLL unlocked
interrupt fires causing "Unexpected DP AUX IRQ 0x01000000 when
not busy" spam in the logs since last 2-3 cycles
- correct the highest bank bit to match downstream device tree for
msm8998
- skip the video mode wait if the timing engine is not enabled. This
was introduced after pre_enable flag for DSI video mode panels
where we would end up waiting for the video mode done interrupt
even before enabling timing engine causing error spam and long
bootup times.
- check the correct return code of irq_of_parse_and_map() in DSI code
- avoid overflow issues in the dpu bandwidth calculation . This was
exposed for high resolution displays and a critical fix to avoid
atomic_check failure
- minor fix to add new lines in DP print messages.
- Fix to fail atomic_check() if the resolution exceeds max mdp clk.
This leads to underflow otherwise if we try to allow that frame.

In the possible_parent_show function, ensure proper handling of the return
value from of_clk_get_parent_name to prevent potential issues arising from
a NULL return.
The current implementation invokes seq_puts directly on the result of
of_clk_get_parent_name without verifying the return value, which can lead
to kernel panic if the function returns NULL.
This patch addresses the concern by introducing a check on the return
value of of_clk_get_parent_name. If the return value is not NULL, the
function proceeds to call seq_puts, providing the returned value as
argument.
However, if of_clk_get_parent_name returns NULL, the function provides a
static string as argument, avoiding the panic.

Commit 9607beb917 ("clk: socfpga: gate: Add a determine_rate hook")
added a determine_rate implementation set to the
clk_hw_determine_rate_no_reparent, but failed to account for the
internal divider that wasn't used before anywhere but in recalc_rate.
This led to inconsistencies between the clock rate stored in
clk_core->rate and the one returned by clk_round_rate() that leverages
determine_rate().
Since that driver seems to be widely used (and thus regression-prone)
and not supporting rate changes (since it's missing a .set_rate
implementation), we can just report the current divider programmed in
the clock but not try to change it in any way.
This should be good enough to fix the issues reported, and if someone
ever wants to allow the divider to change then it should be easy enough
using the clk-divider helpers.

This reverts commit 92e24e0e57.
While the patch itself is correct, it uncovered an issue with fallback
to PS/2 mode, where we were leaving psmouse->fast_reconnect handler set
to psmouse_smbus_reconnect(), which caused crashes.
While discussing various approaches to fix the issue it was noted that
this patch ass undesired delay in the "fast" resume path of PS/2 device,
and it would be better to actually use "reset_delay" option defined in
struct rmi_device_platform_data and have RMI code handle it for SMBus
transport as well. So this patch is being reverted to deal with crashes
and a better solution will be merged shortly.

Commit df8fc4e934 ("kbuild: Enable -fstrict-flex-arrays=3") enabled

[ Miguel: Commit df8fc4e934 ("kbuild: Enable -fstrict-flex-arrays=3")
did it so only conditionally (i.e. only if the C compiler supports
it). This explains what Andrea was seeing: he was compiling with a
modern enough GCC, which enables the option, but with an old enough
Clang. Andrea confirmed this was the case: he was using Clang 14 with
GCC 13; and that Clang 15 worked for him.
While it is possible to construct code (see mailing list for an
example I came up with) where this could break, it is fairly
contrived, and anyway GCC-built kernels with Rust enabled should
only be used for experimentation until we get support for
`rustc_codegen_gcc` and/or GCC Rust. So let's add this for the
time being in case it helps somebody. ]
Add '-fstrict-flex-arrays' to the list of cflags that should be ignored
by bindgen.

Commit 5c0338c687 ("workqueue: restore WQ_UNBOUND/max_active==1
to be ordered") enabled implicit ordered attribute to be added to
WQ_UNBOUND workqueues with max_active of 1. This prevented the changing
of attributes to these workqueues leading to fix commit 0a94efb5ac
("workqueue: implicit ordered attribute should be overridable").
However, workqueue_apply_unbound_cpumask() was not updated at that time.
So sysfs changes to wq_unbound_cpumask has no effect on WQ_UNBOUND
workqueues with implicit ordered attribute. Since not all WQ_UNBOUND
workqueues are visible on sysfs, we are not able to make all the
necessary cpumask changes even if we iterates all the workqueue cpumasks
in sysfs and changing them one by one.
Fix this problem by applying the corresponding change made
to apply_workqueue_attrs_locked() in the fix commit to
workqueue_apply_unbound_cpumask().

The ABI mandates that the %esp register must be a multiple of 16 when
executing a 'call' instruction.
Commit 2ab446336b ("tools/nolibc: i386: shrink _start with _start_c")
simplified the _start function, but it didn't take care of the %esp
alignment, causing SIGSEGV on SSE and AVX programs that use aligned move
instruction (e.g., movdqa, movaps, and vmovdqa).
The 'and $-16, %esp' aligns the %esp at a multiple of 16. Then 'push
%eax' will subtract the %esp by 4; thus, it breaks the 16-byte
alignment. Make sure the %esp is correctly aligned after the push by
subtracting 12 before the push.
Extra:
Add 'add $12, %esp' before the 'and $-16, %esp' to avoid over-estimating
for particular cases as suggested by Willy.
A test program to validate the %esp alignment on _start can be found at:

Fei has reported that KASAN triggers during apply_alternatives() on

__asan_load4()

On machines with 5-level paging, cpu_feature_enabled(X86_FEATURE_LA57)
gets patched. It includes KASAN code, where KASAN_SHADOW_START depends on
__VIRTUAL_MASK_SHIFT, which is defined with cpu_feature_enabled().
KASAN gets confused when apply_alternatives() patches the
KASAN_SHADOW_START users. A test patch that makes KASAN_SHADOW_START
static, by replacing __VIRTUAL_MASK_SHIFT with 56, works around the issue.
Fix it for real by disabling KASAN while the kernel is patching alternatives.

be processed, the termination table is used instead to forward them
from uplink to uplink.

When mlx5e_xdp_xmit is called without the XDP_XMIT_FLUSH set it is
possible that it leaves a mpwqe session open. That is ok during runtime:
the session will be closed on the next call to mlx5e_xdp_xmit. But
having a mpwqe session still open at XDP sq close time is problematic:
the pc counter is not updated before flushing the contents of the
xdpi_fifo. This results in leaking page fragments.
The fix is to always close the mpwqe session at the end of
mlx5e_xdp_xmit, regardless of the XDP_XMIT_FLUSH flag being set or not.

Currently, whenever fw issues a change ownership event, the PF that owns
the fw tracer drops its ownership directly and the other PFs try to pick
up the ownership via what MTRC register suggests.
In some cases, driver releases the ownership of the tracer and reacquires
it later on. Whenever the driver releases ownership of the tracer, fw
issues a change ownership event. This event can be delayed and come after
driver has reacquired ownership of the tracer. Thus the late event will
trigger the tracer owner PF to release the ownership again and lead to a
scenario where no PF is owning the tracer.
To prevent the scenario described above, when handling a change
ownership event, do not drop ownership of the tracer directly, instead
read the fw MTRC register to retrieve the up-to-date owner of the tracer
and set it accordingly in driver level.

With current implementation in single FDB LAG mode all packets are
processed by eswitch 0 rules. As such, 'peer' FDB entries receive the
packets for rules of other eswitches and are responsible for updating the
main entry by sending SWITCHDEV_FDB_ADD_TO_BRIDGE notification from their
background update wq task. However, this introduces a race condition when
non-zero eswitch instance decides to delete a FDB entry, sends
SWITCHDEV_FDB_DEL_TO_BRIDGE notification, but another eswitch's update task
refreshes the same entry concurrently while its async delete work is still
pending on the workque. In such case another SWITCHDEV_FDB_ADD_TO_BRIDGE
event may be generated and entry will remain stuck in FDB marked as
'offloaded' since no more SWITCHDEV_FDB_DEL_TO_BRIDGE notifications are
sent for deleting the peer entries.
Fix the issue by synchronously marking deleted entries with
MLX5_ESW_BRIDGE_FLAG_DELETED flag and skipping them in background update

The cited patch change mlx5 driver so that during probe DMA
operations were performed before pci_enable_device(), and during
teardown DMA operations were performed after pci_disable_device().
DMA operations require PCI to be enabled. Hence, The above leads to
the following oops in PPC systems[1].
On s390x systems, as reported by Niklas Schnelle, this is a problem
because mlx5_pci_init() is where the DMA and coherent mask is set but
mlx5_cmd_init() already does a dma_alloc_coherent(). Thus a DMA
allocation is done during probe before the correct mask is set. This
causes probe to fail initialization of the cmdif SW structs on s390x
after that is converted to the common dma-iommu code. This is because on
s390x DMA addresses below 4 GiB are reserved on current machines and
unlike the old s390x specific DMA API implementation common code
enforces DMA masks.
Fix it by performing the DMA operations during probe after
pci_enable_device() and after the dma mask is set,
and during teardown before pci_disable_device().

kernel-doc emits a warning:
include/uapi/drm/nouveau_drm.h:49: warning: Cannot understand * @NOUVEAU_GETPARAM_EXEC_PUSH_MAX
on line 49 - I thought it was a doc line
We don't have a way to document a macro value via kernel-doc, so
change the "/**" kernel-doc marker to a C comment and format the comment
more like a kernel-doc comment for consistency.
Fixes: d59e75eef5 ("drm/nouveau: exec: report max pushs through getparam")

Pull pin control fixes from Linus Walleij:
"Some pin control fixes for v6.6 which have been stacking up in my
tree.
Dmitry's fix to some locking in the core is the most substantial, that
was a really neat fix.
The rest is the usual assorted spray of minor driver fixes.
- Drop some minor code causing warnings in the Lantiq driver
- Fix out of bounds write in the Nuvoton driver
- Fix lost IRQs with CONFIG_PM in the Starfive driver
- Fix a locking issue in find_pinctrl()
- Revert a regressive Tegra debug patch
- Fix the Renesas RZN1 pin muxing"

Randy reported a randconfig build issue against linux-next:
WARNING: unmet direct dependencies detected for ERRATA_ANDES
Depends on [n]: RISCV_ALTERNATIVE [=n] && RISCV_SBI [=y]
Selected by [y]:
- ARCH_R9A07G043 [=y] && SOC_RENESAS [=y] && RISCV [=y] && NONPORTABLE [=y] && RISCV_SBI [=y]
../arch/riscv/errata/andes/errata.c:59:54: warning: 'struct alt_entry' declared inside parameter list will not be visible outside of this definition or declaration
59 | void __init_or_module andes_errata_patch_func(struct alt_entry *begin, struct alt_entry *end,
On RISC-V, alternatives are not usable in XIP kernels, which this
randconfig happened to select. Rather than add a check for whether
alternatives are available before selecting the ERRATA_ANDES config
option, rework the R9A07G043 Kconfig entry to depend on the
configuration options required to support its non-standard cache
coherency implementation.
Without these options enabled, the SoC is effectively non-functional to
begin with, so there's an extra benefit in preventing the creation of
non-functional kernels.
The "if RISCV_DMA_NONCOHERENT" can be dropped, as ERRATA_ANDES_CMO will
select it.
