f1a325d281 soc: qcom: geni-se: Introduce helper API for attaching power domains
The GENI Serial Engine drivers (I2C, SPI, and SERIAL) currently handle
the attachment of power domains. This often leads to duplicated code
logic across different driver probe functions.

Introduce a new helper API, geni_se_domain_attach(), to centralize
the logic for attaching "power" and "perf" domains to the GENI SE
device.

8f4ce470ff soc: qcom: geni-se: Add resources activation/deactivation helpers
The GENI SE protocol drivers (I2C, SPI, UART) implement similar resource
activation/deactivation sequences independently, leading to code
duplication.

Introduce geni_se_resources_activate()/geni_se_resources_deactivate() to
power on/off resources.The activate function enables ICC, clocks, and TLMM
whereas the deactivate function disables resources in reverse order
including OPP rate reset, clocks, ICC and TLMM.

e5f54cda9d soc: qcom: geni-se: Handle core clk in geni_se_clks_off() and geni_se_clks_on()
Currently, core clk is handled individually in protocol drivers like
the I2C driver. Move this clock management to the common clock APIs
(geni_se_clks_on/off) that are already present in the common GENI SE
driver to maintain consistency across all protocol drivers.

Core clk is now properly managed alongside the other clocks (se->clk
and wrapper clocks) in the fundamental clock control functions,
eliminating the need for individual protocol drivers to handle this
clock separately.

Add a new function geni_icc_set_bw_ab() that allows callers to set
average bandwidth values for all ICC (Interconnect) paths in a single

average bandwidth values and applies them to the respective ICC paths.

This provides a more convenient API for drivers that need to configure
specific average bandwidth values.

d922113ef9 soc: qcom: ice: Fix race between qcom_ice_probe() and of_qcom_ice_get()
The current platform driver design causes probe ordering races with
consumers (UFS, eMMC) due to ICE's dependency on SCM firmware calls. If ICE
probe fails (missing ICE SCM or DT registers), devm_of_qcom_ice_get() loops
with -EPROBE_DEFER, leaving consumers non-functional even when ICE should
be gracefully disabled. devm_of_qcom_ice_get() doesn't know if the ICE
driver probe has failed due to above reasons or it is waiting for the SCM
driver.

Moreover, there is no devlink dependency between ICE and consumer drivers
as 'qcom,ice' is not considered as a DT 'supplier'. So the consumer drivers
have no idea of when the ICE driver is going to probe.

To address these issues, store the error pointer in a global xarray with
ice node phandle as a key during probe in addition to the valid ice pointer
and synchronize both qcom_ice_probe() and of_qcom_ice_get() using a mutex.

If the xarray entry is NULL, then it implies that the driver is not
probed yet, so return -EPROBE_DEFER. If it has any error pointer, return
that error pointer directly. Otherwise, add the devlink as usual and return
the valid pointer to the consumer.

Xarray is used instead of platform drvdata, since driver core frees the
drvdata during probe failure. So it cannot be used to pass the error
pointer to the consumers.

Note that this change only fixes the standalone ICE DT node bindings and
not the ones with 'ice' range embedded in the consumer nodes, where there
is no issue.

(zynqmp_pm_init_suspend_work and zynqmp_pm_init_restart_work) used by

This created a race window where, if the firmware triggered an event
immediately after registration but before allocation, the callback
(suspend_event_callback or subsystem_restart_event_callback) would
dereference a NULL pointer in work_pending(), leading to a crash.

Fix this by allocating and initializing the work structures before

  to this region is enabled by default. CPU access can be disabled,
  after which reads will show the same stale value for all addresses,
  while writes are ignored.

  The mux value for this region is different from previous generations.

- The SRAM C region is an alias of the first 128 KB of VE SRAM, plus 64
  KB of DE SRAM. The latter is otherwise unaccessible from the CPU. When
  CPU access is disabled, the whole region reads as zero, while writes
  are ignored.

  The mux value for this region is the same as on the A64 and H6.

Add data for the VE SRAM. The register values were taken from the BSP

67890da74d soc: sunxi: sram: Allow SRAM to be claimed multiple times
On the H616, the SRAM C region is an alias mapping to part of the VE
SRAM (accessible in whole at a different address) and part of the DE
SRAM (otherwise unaccessible). As such both the VE and DE need to claim
this SRAM region to prevent access from the CPU.

The SRAM claim API is designed so that a "claim" routes the SRAM to the
peripheral device, disabling access from the CPU. So long as the written
register value is the same for all the claimants involved, allowing
multiple or repeated claims is trivial. This is indeed the case for all
supported SRAM regions. The only known SRAM region to have multiple
different settings is the SRAM C2 region; this can be claimed by the AE,
CE, or ACE (assumed to be AE + CE). This region is not supported, and
likely will never be needed nor supported, as there is no documentation
for the peripherals involved.

Change the SRAM region "claimed" field from a boolean to a reference
count. A claim will increment the count, while a release decreases it.
The first claim will trigger the register value write. The driver
otherwise behaves as before.

Linus Torvalds
4793dae01f Driver core changes for 7.1-rc1
- debugfs:
   - Fix NULL pointer dereference in debugfs_create_str()
   - Fix misplaced EXPORT_SYMBOL_GPL for debugfs_create_str()
   - Fix soundwire debugfs NULL pointer dereference from uninitialized
     firmware_file
 
 - device property:
   - Make fwnode flags modifications thread safe; widen the field to
     unsigned long and use set_bit() / clear_bit() based accessors
   - Document how to check for the property presence
 
 - devres:
   - Separate struct devres_node from its "subclasses" (struct devres,
     struct devres_group); give struct devres_node its own release and
     free callbacks for per-type dispatch
   - Introduce struct devres_action for devres actions, avoiding the
     ARCH_DMA_MINALIGN alignment overhead of struct devres
   - Export struct devres_node and its init/add/remove/dbginfo
     primitives for use by Rust Devres<T>
   - Fix missing node debug info in devm_krealloc()
   - Use guard(spinlock_irqsave) where applicable; consolidate unlock
     paths in devres_release_group()
 
 - driver_override:
   - Convert PCI, WMI, vdpa, s390/cio, s390/ap, and fsl-mc to the
     generic driver_override infrastructure, replacing per-bus
     driver_override strings, sysfs attributes, and match logic; fixes
     a potential UAF from unsynchronized access to driver_override in
     bus match() callbacks
   - Simplify __device_set_driver_override() logic
 
 - kernfs:
   - Send IN_DELETE_SELF and IN_IGNORED inotify events on kernfs
     file and directory removal
   - Add corresponding selftests for memcg
 
 - platform:
   - Allow attaching software nodes when creating platform devices via
     a new 'swnode' field in struct platform_device_info
   - Add kerneldoc for struct platform_device_info
 
 - software node:
   - Move software node initialization from postcore_initcall() to
     driver_init(), making it available early in the boot process
   - Move kernel_kobj initialization (ksysfs_init) earlier to support
     the above
   - Remove software_node_exit(); dead code in a built-in unit
 
 - SoC:
   - Introduce of_machine_read_compatible() and of_machine_read_model()
     OF helpers and export soc_attr_read_machine() to replace direct
     accesses to of_root from SoC drivers; also enables
     CONFIG_COMPILE_TEST coverage for these drivers
 
 - sysfs:
   - Constify attribute group array pointers to
     'const struct attribute_group *const *' in sysfs functions,
     device_add_groups() / device_remove_groups(), and struct class
 
 - Rust:
   - Devres:
     - Embed struct devres_node directly in Devres<T> instead of going
       through devm_add_action(), avoiding the extra allocation and
       the unnecessary ARCH_DMA_MINALIGN alignment
 
   - I/O:
     - Turn IoCapable from a marker trait into a functional trait
       carrying the raw I/O accessor implementation (io_read /
       io_write), providing working defaults for the per-type Io
       methods
     - Add RelaxedMmio wrapper type, making relaxed accessors usable
       in code generic over the Io trait
     - Remove overloaded per-type Io methods and per-backend macros
       from Mmio and PCI ConfigSpace
 
   - I/O (Register):
     - Add IoLoc trait and generic read/write/update methods to the Io
       trait, making I/O operations parameterizable by typed locations
     - Add register! macro for defining hardware register types with
       typed bitfield accessors backed by Bounded values; supports
       direct, relative, and array register addressing
     - Add write_reg() / try_write_reg() and LocatedRegister trait
     - Update PCI sample driver to demonstrate the register! macro
 
         Example:
 
         ```
             register! {
                 /// UART control register.
                 CTRL(u32) @ 0x18 {
                     /// Receiver enable.
                     19:19   rx_enable => bool;
                     /// Parity configuration.
                     14:13   parity ?=> Parity;
                 }
 
                 /// FIFO watermark and counter register.
                 WATER(u32) @ 0x2c {
                     /// Number of datawords in the receive FIFO.
                     26:24   rx_count;
                     /// RX interrupt threshold.
                     17:16   rx_water;
                 }
             }
 
             impl WATER {
                 fn rx_above_watermark(&self) -> bool {
                     self.rx_count() > self.rx_water()
                 }
             }
 
             fn init(bar: &pci::Bar<BAR0_SIZE>) {
                 let water = WATER::zeroed()
                     .with_const_rx_water::<1>(); // > 3 would not compile
                 bar.write_reg(water);
 
                 let ctrl = CTRL::zeroed()
                     .with_parity(Parity::Even)
                     .with_rx_enable(true);
                 bar.write_reg(ctrl);
             }
 
             fn handle_rx(bar: &pci::Bar<BAR0_SIZE>) {
                 if bar.read(WATER).rx_above_watermark() {
                     // drain the FIFO
                 }
             }
 
             fn set_parity(bar: &pci::Bar<BAR0_SIZE>, parity: Parity) {
                 bar.update(CTRL, |r| r.with_parity(parity));
             }
         ```
 
   - IRQ:
     - Move 'static bounds from where clauses to trait declarations
       for IRQ handler traits
 
   - Misc:
     - Enable the generic_arg_infer Rust feature
     - Extend Bounded with shift operations, single-bit bool conversion,
       and const get()
 
 - Misc:
   - Make deferred_probe_timeout default a Kconfig option
   - Drop auxiliary_dev_pm_ops; the PM core falls back to driver PM
     callbacks when no bus type PM ops are set
   - Add conditional guard support for device_lock()
   - Add ksysfs.c to the DRIVER CORE MAINTAINERS entry
   - Fix kernel-doc warnings in base.h
   - Fix stale reference to memory_block_add_nid() in documentation

        typed bitfield accessors backed by Bounded values; supports
        direct, relative, and array register addressing
      - Add write_reg() / try_write_reg() and LocatedRegister trait
      - Update PCI sample driver to demonstrate the register! macro

         Example:

         ```

                     19:19   rx_enable => bool;
                     /// Parity configuration.
                     14:13   parity ?=> Parity;
                 }

                 /// FIFO watermark and counter register.
                 WATER(u32) @ 0x2c {

             }

             fn set_parity(bar: &pci::Bar<BAR0_SIZE>, parity: Parity) {

        conversion, and const get()

  Misc:
   - Make deferred_probe_timeout default a Kconfig option

     callbacks when no bus type PM ops are set
   - Add conditional guard support for device_lock()

Microchip:
 Add coverage for the pic64gx in the system controller and syscons.
 Add a interrupt mux driver (akin to the one that Renesas recently added)
 that fixes a problem where the platform never properly modelled gpio
 interrupts. There's a gpio driver change here that Bartosz has acked
 that adds the interrupt support to the GPIO driver itself.

66ec836279 ASoC: qcom: Constify GPR packet being send over GPR interface
gpr_send_pkt() and pkt_router_send_svc_pkt() only send the GPR packet
they receive, without any need to actually modify it, so mark the
pointer to GPR packet as pointer to const for code safety and code
self-documentation.  Several users of this interface can follow up and
also operate on pointer to const.

a0fe29d20e soc: fsl: qe: panic on ioremap() failure in qe_reset()
When ioremap() fails in qe_reset(), the global pointer qe_immr remains
NULL, leading to a subsequent NULL pointer dereference when the pointer
is accessed. Since this happens early in the boot process, a failure to
map a few bytes of I/O memory indicates a fatal error from which the
system cannot recover.

Follow the same pattern as qe_sdma_init() and panic immediately when
ioremap() fails. This avoids a silent NULL pointer dereference later
and makes the error explicit.

cd3c4670db soc: qcom: aoss: compare against normalized cooling state
qmp_cdev_set_cur_state() normalizes the requested state to a boolean
(cdev_state = !!state). The existing early-return check compares
qmp_cdev->state == state, which can be wrong if state is non-boolean
(any non-zero value). Compare qmp_cdev->state against cdev_state instead,
so the check matches the effective state and avoids redundant updates.

24e7625df5 soc: qcom: llcc: fix v1 SB syndrome register offset
The llcc_v1_edac_reg_offset table uses 0x2304c for trp_ecc_sb_err_syn0,
which is inconsistent with the surrounding TRP ECC registers (0x2034x)
and with llcc_v2_1_edac_reg_offset, where trp_ecc_sb_err_syn0 is 0x2034c
adjacent to trp_ecc_error_status0/1 at 0x20344/0x20348.

Use 0x2034c for llcc v1 so the SB syndrome register follows the expected
+0x4 progression from trp_ecc_error_status1. This fixes EDAC reading the
wrong register for SB syndrome reporting.

e8014b2c83 soc/tegra: pmc: Add IO pads for Tegra264
Populate the IO pads and pins for Tegra264. Tegra264 has internal 1.8V
and 0.6V regulators that must be enabled when selecting the 1.8V mode
for the sdmmc1-hv IO pad. To support this a new 'ena_1v8' member is
added to the 'tegra_io_pad_vctrl' structure to populate the bits that
need to be set to enable these internal regulators. Although this is
enabling 1.8V (bit 1) and 0.6V (bit 2) regulators, it is simply called
'ena_1v8' because these are both enabled for 1.8V operation. Note that
these internal regulators are disabled when not using 1.8V mode.

edded7a903 soc/tegra: pmc: Refactor IO pad voltage control
For Tegra devices, only a subset of IO pads can be configured for 1.8V
or 3.3V. Therefore, in the 'tegra_io_pad_soc' structure for Tegra SoCs
either all or most of the 'voltage' entries are set to UINT_MAX to
indicate the IO pad voltage cannot be configured. So for the majority of
IO pads this configuration is not applicable. However, refactoring the
IO pad data to move this parameter into a separate structure does not
make sense because the benefits are marginal.

Support for the Tegra264 IO pads is currently missing and the control
for configuring the voltage for the IO pads for Tegra264 has changed.
Instead of having a single register that is used for setting the IO pad
voltage for all IO pads, there is now a register associated with the
specific IO pad. For Tegra264, there is now only one IO pad that can be
configured for 1.8V or 3.3V which is the sdmmc1-hv. While we could make
this work with by adding a new SoC flag, the implementation will be a
bit cumbersome. Therefore, it now seems reasonable to refactor the IO
pad code. Hence, introduce a new 'tegra_io_pad_vctrl' structure that
contains the register offset and bit for enabling/disabling 3.3V mode
and move the existing voltage control data for supported SoCs to this
structure. This has an added benefit of simplifying the code in the
functions tegra_io_pad_get_voltage and tegra_io_pad_set_voltage.

d487085006 soc: qcom: pmic_glink_altmode: Fix SVID=DP && unconnected edge case
The commit referenced in Fixes started evaluating the value of
alt_port->mux_ctrl before checking the active SVID. This led to
drm_aux_hpd_bridge_notify() no longer being called for the 'DP unplug'
case.

Perhaps somewhat interestingly, the firmware sends a notification with
SVID=DP, mux_ctrl=MUX_CTRL_STATE_NO_CONN and pin_assignment=0 on
unplug. 'pin_assignment' was previously interpreted as a bitfield
excerpt from the second byte of the DP pg_altmode payload (and stored
as an u8).

That value is used in pmic_glink_altmode_sc8280xp_notify(), decremented
by 1 (DPAM_HPD_A). Previously, this would result in an u8 underflow
that would rollover to 0xff (which prior to the Fixes patch would have
caused a pmic_glink_altmode_safe() and 'disconnected' bridge
notification). That check was removed, without a replacement.

Resolve this issue by making sure the SID=DP && mux_ctrl=NO_CONN combo
once again results in a HPD bridge notification.

42c4cf5d48 soc: qcom: smp2p: Add support for smp2p v2
smp2p v2 adds support for allowing remote processors to write outbound
smp2p items without completing the feature negotiation. This is required
for processors that start before linux to write out signals like error
and clock ready and unblock their bootup.

If a remote processor only supports v1, smp2p can version down by
mirroring the peer version during the negotiation stage.

When using smp2p version 2, the remote does not wait for the ssr ack
before setting the items. To accommodate this, set the last_value of all
the entries to 0 when SSR is detected. This forces smp2p to detect the
new values written by the remote. Because the SSR ack is skipped, the
down transition of bits is missed in smp2p version 2.

A remoteproc booted during earlier boot stages such as UEFI or the
bootloader, may need to be attached to without restarting the remoteproc
hardware. To do this the remoteproc will need to check the ready and
handover states in smp2p without an interrupt notification. Create
qcom_smp2p_start_in() to initialize the shadow state without notifying
clients because these early events happened in the past.

Add support for the .irq_get_irqchip_state callback so remoteproc can

014077044e soc: fsl: qbman: fix race condition in qman_destroy_fq
When QMAN_FQ_FLAG_DYNAMIC_FQID is set, there's a race condition between
fq_table[fq->idx] state and freeing/allocating from the pool and
WARN_ON(fq_table[fq->idx]) in qman_create_fq() gets triggered.

Indeed, we can have:
         Thread A                             Thread B
    qman_destroy_fq()                    qman_create_fq()
      qman_release_fqid()
        qman_shutdown_fq()
        gen_pool_free()
           -- At this point, the fqid is available again --
                                           qman_alloc_fqid()
           -- so, we can get the just-freed fqid in thread B --
                                           fq->fqid = fqid;
                                           fq->idx = fqid * 2;
                                           WARN_ON(fq_table[fq->idx]);
                                           fq_table[fq->idx] = fq;
     fq_table[fq->idx] = NULL;

And adding some logs between qman_release_fqid() and
fq_table[fq->idx] = NULL makes the WARN_ON() trigger a lot more.

To prevent that, ensure that fq_table[fq->idx] is set to NULL before
gen_pool_free() is called by using smp_wmb().

7ec1bd3d9b soc: aspeed: socinfo: Mask table entries for accurate SoC ID matching
The siliconid_to_name() function currently masks the input silicon ID
with 0xff00ffff, but compares it against unmasked table entries. This
causes matching to fail if the table entries contain non-zero values in
the bits covered by the mask (bits 16-23).

Update the logic to apply the 0xff00ffff mask to the table entries
during comparison. This ensures that only the relevant model and
revision bits are considered, providing a consistent match across
different manufacturing batches.

32a92f8c89 Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
This converts some of the visually simpler cases that have been split
over multiple lines.  I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.

Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script.  I probably had made it a bit _too_ trivial.

So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.

The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

which sets system defaults for some settings like disabling the automatic

 One is a corrected register-offset and the other makes the code actually
 look for all matched GRF instances, which it didn't do before.

Merge tag 'v6.20-rockchip-drivers1' of https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into soc/drivers

Two fixes for the default-settings code for the General-Register-Files,
which sets system defaults for some settings like disabling the automatic
jtag/sdmmc switching.

One is a corrected register-offset and the other makes the code actually
look for all matched GRF instances, which it didn't do before.

 "failed to probe" from "not yet probed", did not change the

 SMEM as always available. Clients might then proceed to interact with
 SMEM in codepaths that aren't suited to cope with -EPROBE_DEFER.

f2090ebdb5 soc: qcom: smem: fix qcom_smem_is_available and check if __smem is valid
Commit 7a94d5f31b ("soc: qcom: smem: better track SMEM uninitialized
state") changed the usage of __smem and init now as an error pointer
instead of NULL.

qcom_smem_is_available() wasn't updated to reflect this change and also
.qcom_smem_remove doesn't reset it on module exit.

Update both entry to reflect new handling of __smem.

733f0303c2 Qualcomm driver updates for v6.20
Support multiple wait queues in the SCM firmware interface and provide
 discovery of the wait queue interrupt to deal with the cases where
 bootloader didn't patch the DeviceTree with the IRQ information.
 
 Refactor the MDT loader and the SCM driver's peripheral authentication
 service interface and introduce support for passing a remoteproc
 resource table to the firmware. The remoteproc patches that uses this
 and uses this to configure the IOMMU are included here due to
 bidirectional dependencies. The end result is remoteproc support on the
 Glymur platform.
 
 Enable QSEECOM and thereby UEFI variable access, on the Surface Pro 11.
 
 Make the QMI interface endianness aware, to support ath1Xk on big endian
 machines.
 
 Add the Glymur support in LLCC driver.

Qualcomm driver updates for v6.20

Support multiple wait queues in the SCM firmware interface and provide
discovery of the wait queue interrupt to deal with the cases where
bootloader didn't patch the DeviceTree with the IRQ information.

Refactor the MDT loader and the SCM driver's peripheral authentication
service interface and introduce support for passing a remoteproc
resource table to the firmware. The remoteproc patches that uses this
and uses this to configure the IOMMU are included here due to
bidirectional dependencies. The end result is remoteproc support on the
Glymur platform.

Enable QSEECOM and thereby UEFI variable access, on the Surface Pro 11.

Make the QMI interface endianness aware, to support ath1Xk on big endian
machines.

Add the Glymur support in LLCC driver.

f8d91cfb93 soc/tegra: Changes for v6.20-rc1
This series primarily refactors the Tegra PMC driver to eliminate
 reliance on a global variable, transitioning to passing the tegra_pmc
 context explicitly across clocks, powergates, sysfs/debugfs interfaces,
 and power management callbacks. Additionally, it resolves a warning
 during system resume by deferring an unsafe generic_handle_irq() call to
 a hard IRQ context using irq_work.

65d5727645 soc: fsl: qe: qe_ports_ic: Consolidate chained IRQ handler install/remove
The driver currently sets the handler data and the chained handler in
two separate steps. This creates a theoretical race window where an
interrupt could fire after the handler is set but before the data is
assigned, leading to a NULL pointer dereference.

Replace the two calls with irq_set_chained_handler_and_data() to set
both the handler and its data atomically under the irq_desc->lock.

soc: mediatek: mtk-cmdq: Add mminfra_offset adjustment for DRAM addresses
Since GCE has been moved to MMINFRA in MT8196, all transactions from
MMINFRA to DRAM will have their addresses adjusted by subtracting a
mminfra_offset.

Therefore, the CMDQ helper driver needs to get the mminfra_offset value
of the SoC from cmdq_mbox_priv of cmdq_pkt and then add it to the DRAM
address when generating instructions to ensure GCE accesses the correct
DRAM address. CMDQ users can then call CMDQ helper APIs as usual.

soc: mediatek: mtk-cmdq: Extend cmdq_pkt_write API for SoCs without subsys ID
This patch extends the cmdq_pkt_write API to support SoCs that do not
have subsys ID mapping by introducing new register write APIs:
- cmdq_pkt_write_pa() and cmdq_pkt_write_subsys() replace
  cmdq_pkt_write()
- cmdq_pkt_write_mask_pa() and cmdq_pkt_write_mask_subsys() replace
  cmdq_pkt_write_mask()

To ensure consistent function pointer interfaces, both
cmdq_pkt_write_pa() and cmdq_pkt_write_subsys() provide subsys and
pa_base parameters. This unifies how register writes are invoked,
regardless of whether subsys ID is supported by the device.

All GCEs support writing registers by PA (with mask) without subsys,
but this requires extra GCE instructions to convert the PA into a GCE
readable format, reducing performance compared to using subsys directly.
Therefore, subsys is preferred for register writes when available.

API documentation and function pointer declarations in cmdq_client_reg
have been updated. The original write APIs will be removed after all
CMDQ users transition to the new interfaces.

soc: mediatek: mtk-cmdq: Add pa_base parsing for hardware without subsys ID support
When GCE executes instructions, it typically locates the corresponding
hardware register using the subsys ID. For hardware that does not
support subsys ID, the subsys ID is set to an invalid value, and the
physical address must be used to generate GCE instructions.

The main advantage of using subsys ID is to reduce the number of
instructions. Without subsys ID, an additional `ASSIGN` instruction
is needed to assign the high bytes of the physical address, which can
impact performance if too many instructions are required. However, if
the hardware does not support subsys ID, using the physical address
is the only option to achieve the same functionality.

This commit adds a pa_base parsing flow to the cmdq_client_reg structure
to handle hardware without subsys ID support.

e6d96073af soc/tegra: pmc: Fix unsafe generic_handle_irq() call
Currently, when resuming from system suspend on Tegra platforms,
the following warning is observed:

WARNING: CPU: 0 PID: 14459 at kernel/irq/irqdesc.c:666
Call trace:
 handle_irq_desc+0x20/0x58 (P)
 tegra186_pmc_wake_syscore_resume+0xe4/0x15c
 syscore_resume+0x3c/0xb8
 suspend_devices_and_enter+0x510/0x540
 pm_suspend+0x16c/0x1d8

The warning occurs because generic_handle_irq() is being called from
a non-interrupt context which is considered as unsafe.

Fix this warning by deferring generic_handle_irq() call to an IRQ work
which gets executed in hard IRQ context where generic_handle_irq()
can be called safely.

When PREEMPT_RT kernels are used, regular IRQ work (initialized with
init_irq_work) is deferred to run in per-CPU kthreads in preemptible
context rather than hard IRQ context. Hence, use the IRQ_WORK_INIT_HARD
variant so that with PREEMPT_RT kernels, the IRQ work is processed in
hardirq context instead of being deferred to a thread which is required
for calling generic_handle_irq().

On non-PREEMPT_RT kernels, both init_irq_work() and IRQ_WORK_INIT_HARD()
execute in IRQ context, so this change has no functional impact for
standard kernel configurations.

Introduce a new PAS context-aware function, qcom_mdt_pas_load(), for
remote processor drivers. This function utilizes the PAS context
pointer returned from qcom_scm_pas_ctx_init() to perform firmware
metadata verification and memory setup via SMC calls.

The qcom_mdt_pas_load() and qcom_mdt_load() functions are largely
similar, but the former is designed for clients using the PAS
context-based data structure. Over time, all users of qcom_mdt_load()
can be migrated to use qcom_mdt_pas_load() for consistency and
improved abstraction.

As the remoteproc PAS driver (qcom_q6v5_pas) has already adopted the
PAS context-based approach, update it to use qcom_mdt_pas_load().

b13d8baf56 remoteproc: pas: Replace metadata context with PAS context structure
As a superset of the existing metadata context, the PAS context
structure enables both remoteproc and non-remoteproc subsystems to
better support scenarios where the SoC runs with or without the Gunyah
hypervisor. To reflect this, relevant SCM and metadata functions are
updated to incorporate PAS context awareness and remove metadata context
data structure completely.

f0bcd784e1 soc: fsl: qe: Add an interrupt controller for QUICC Engine Ports
The QUICC Engine provides interrupts for a few I/O ports. This is
handled via a separate interrupt ID and managed via a triplet of
dedicated registers hosted by the SoC.

Implement an interrupt driver for it so that those IRQs can then
be linked to the related GPIOs.

soc: mediatek: mtk-dvfsrc: Rework bandwidth calculations
The code, as it is, plays fast and loose with bandwidth units. It also
doesn't specify its constraints in the actual maximum hardware value,
but as some roundabout thing that then ends up multiplied into the
actual hardware value constraint after some indirections. In part, this
is due to the use of individual members for storing each limit, instead
of making it possible to index them by type.

Rework all of this by adding const array members indexed by the
bandwidth type enum to the soc_data struct. This array expresses the
actual hardware value limitations, not a factor thereof.

Use the clamp function macro to clamp the values between the minimum and
maximum constraints after all the calculations, which also means the
code doesn't write nonsense to a hardware register when the math is
wrong, as it'll constrain after all the calculations.

Pass the type as the actual enum type as well, and not as an int. If
there's some type checking that can be extracted from the function
signature, then we may as well use it.

Don't needlessly explicitly cast return values to the return type
either; this is both unnecessary and makes it harder to spot type safety
issues.
