Pull drm fixes from Dave Airlie:
 "Lots going on for rc2, ivpu has a bunch of stabilisation and debugging
  work, then amdgpu and xe are the main fixes. i915, exynos have a few,
  then some misc panel and bridge fixes.

  Worth mentioning are three regressions. One of the nouveau fixes in
  6.7 for a serious deadlock had side effects, so I guess we will bring
  back the deadlock until I can figure out what should be done properly.
  There was a scheduler regression vs amdgpu which was reported in a few
  places and is now fixed. There was an i915 vs simpledrm problem
  resulting in black screens, that is reverted also.

  I'll be working on a proper nouveau fix, it kinda looks like one of
  those cases where someone tried to use an atomic where they should
  have probably used a lock, but I'll see.

8ad2c84e2e Arm FF-A fixes for v6.8 
Quite a few fixes addressing issues around missing RW lock initialisation
 in ffa_setup_partitions(), missing check for xa_load() return value,
 use of xa_insert instead of xa_store to flag case of duplicate insertion.
 It also simplifies ffa_partitions_cleanup() with xa_for_each() and xa_erase()
 instead of xa_extract() and kfree(). Finally it includes fixes around
 handling of partitions setup failures during initialisation.

d1b163aa07 Revert "drivers/firmware: Move sysfb_init() from device_initcall to subsys_initcall_sync" 
This reverts commit 60aebc9559.

Commit 60aebc9559 ("drivers/firmware: Move sysfb_init() from
device_initcall to subsys_initcall_sync") messes up initialization order
of the graphics drivers and leads to blank displays on some systems. So
revert the commit.

To make the display drivers fully independent from initialization
order requires to track framebuffer memory by device and independently
from the loaded drivers. The kernel currently lacks the infrastructure
to do so.

ace760d9c0 firmware: arm_ffa: Use xa_insert() and check for result 
While adding new partitions descriptors to the XArray the outcome of the
stores should be checked and, in particular, it has also to be ensured
that an existing entry with the same index was not already present, since
partitions IDs are expected to be unique.

Use xa_insert() instead of xa_store() since it returns -EBUSY when the
index is already in use and log an error when that happens.

437a310b22 firmware: arm_scmi: Check mailbox/SMT channel for consistency 
On reception of a completion interrupt the shared memory area is accessed
to retrieve the message header at first and then, if the message sequence
number identifies a transaction which is still pending, the related
payload is fetched too.

When an SCMI command times out the channel ownership remains with the
platform until eventually a late reply is received and, as a consequence,
any further transmission attempt remains pending, waiting for the channel
to be relinquished by the platform.

Once that late reply is received the channel ownership is given back
to the agent and any pending request is then allowed to proceed and
overwrite the SMT area of the just delivered late reply; then the wait
for the reply to the new request starts.

It has been observed that the spurious IRQ related to the late reply can
be wrongly associated with the freshly enqueued request: when that happens
the SCMI stack in-flight lookup procedure is fooled by the fact that the
message header now present in the SMT area is related to the new pending
transaction, even though the real reply has still to arrive.

This race-condition on the A2P channel can be detected by looking at the
channel status bits: a genuine reply from the platform will have set the
channel free bit before triggering the completion IRQ.

Add a consistency check to validate such condition in the A2P ISR.

Here is the big set of char/misc and other driver subsystem changes for
 6.8-rc1.  Lots of stuff in here, but first off, you will get a merge
 conflict in drivers/android/binder_alloc.c when merging this tree due to
 changing coming in through the -mm tree.
 
 The resolution of the merge issue can be found here:
 	https://lore.kernel.org/r/20231207134213.25631ae9@canb.auug.org.au
 or in a simpler patch form in that thread:
 	https://lore.kernel.org/r/ZXHzooF07LfQQYiE@google.com
 
 If there are issues with the merge of this file, please let me know.
 
 Other than lots of binder driver changes (as you can see by the merge
 conflicts) included in here are:
  - lots of iio driver updates and additions
  - spmi driver updates
  - eeprom driver updates
  - firmware driver updates
  - ocxl driver updates
  - mhi driver updates
  - w1 driver updates
  - nvmem driver updates
  - coresight driver updates
  - platform driver remove callback api changes
  - tags.sh script updates
  - bus_type constant marking cleanups
  - lots of other small driver updates
 
 All of these have been in linux-next for a while with no reported issues
 (other than the binder merge conflict.)

f6597d1706 SoC: driver updates for 6.8 
A new drivers/cache/ subsystem is added to contain drivers for abstracting
 cache flush methods on riscv and potentially others, as this is needed for
 handling non-coherent DMA but several SoCs require nonstandard hardware
 methods for it.
 
 op-tee gains support for asynchronous notification with FF-A, as well
 as support for a system thread for executing in secure world.
 
 The tee, reset, bus, memory and scmi subsystems have a couple of minor
 updates.
 
 Platform specific soc driver changes include:
 
  - Samsung Exynos gains driver support for Google GS101 (Tensor G1)
    across multiple subsystems
 
  - Qualcomm Snapdragon gains support for SM8650 and X1E along with
    added features for some other SoCs
 
  - Mediatek adds support for "Smart Voltage Scaling" on MT8186 and MT8195,
    and driver support for MT8188 along with some code refactoring.
 
  - Microchip Polarfire FPGA support for "Auto Update" of the FPGA bitstream
 
  - Apple M1 mailbox driver is rewritten into a SoC driver
 
  - minor updates on amlogic, mvebu, ti, zynq, imx, renesas and hisilicon

  - Allow ACPI Notify () handlers to run on all CPUs and clean up the
    ACPI interface for deferred events processing (Rafael J. Wysocki).
 
  - Switch over the ACPI EC driver to using a threaded handler for the
    dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki).
 
  - Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock to
    keep local interrupts on (Rafael J. Wysocki).
 
  - Adjust the USB4 _OSC handshake to correctly handle cases in which
    certain types of OS control are denied by the platform (Mika
    Westerberg).
 
  - Correct and clean up the generic function for parsing ACPI data-only
    tables with array structure (Yuntao Wang).
 
  - Modify acpi_dev_uid_match() to support different types of its second
    argument and adjust its users accordingly (Raag Jadav).
 
  - Clean up code related to acpi_evaluate_reference() and ACPI device
    lists (Rafael J. Wysocki).
 
  - Use generic ACPI helpers for evaluating trip point temperature
    objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
    Bergmann).
 
  - Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
    zone driver (Jeff Brasen).
 
  - Modify the ACPI LPIT table handling code to avoid u32 multiplication
    overflows in state residency computations (Nikita Kiryushin).

    injection code (Avadhut Naik).
 
  - Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous memory
    failure events, so they are handled differently from the asynchronous
    ones (Shuai Xue).
 
  - Fix NULL pointer dereference check in the ACPI extlog driver (Prarit
    Bhargava).
 
  - Adjust the ACPI extlog driver to clear the Extended Error Log status
    when RAS_CEC handled the error (Tony Luck).
 
  - Add IRQ override quirks for some Infinity laptops and for TongFang
    GMxXGxx (David McFarland, Hans de Goede).
 
  - Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is not
    the same as one of the real pxm values (Yuntao Wang).
 
  - Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
    driver so as to prevent miscalculation of the values in the clock
    divider (Andy Shevchenko).
 
  - Adjust comments in the ACPI watchdog driver to prevent kernel-doc
    from complaining during documentation builds (Randy Dunlap).
 
  - Make the ACPI button driver send wakeup key events to user space in
    addition to power button events on systems that can be woken up by
    the power button (Ken Xue).
 
  - Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full
    structure field (Dmitry Antipov).

Pull ACPI updates from Rafael Wysocki:
 "From the new features standpoint, the most significant change here is
  the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
  device enumeration code that will allow MIPI cameras to be enumerated
  through the platform firmware on systems using ACPI.

  Also significant is the switch-over to threaded interrupt handlers for
  the ACPI SCI and the dedicated EC interrupt (on systems where the
  former is not used) which essentially allows all ACPI code to run with
  local interrupts enabled. That should improve responsiveness
  significantly on systems where multiple GPEs are enabled and the
  handling of one SCI involves many I/O address space accesses which
  previously had to be carried out in one go with disabled interrupts on
  the local CPU.

  Apart from the above, the ACPI thermal zone driver will use the
  Thermal fast Sampling Period (_TFP) object if available, which should
  allow temperature changes to be followed more accurately on some
  systems, the ACPI Notify () handlers can run on all CPUs (not just on
  CPU0), which should generally speed up the processing of events
  signaled through the ACPI SCI, and the ACPI power button driver will
  trigger wakeup key events via the input subsystem (on systems where it
  is a system wakeup device)

  In addition to that, there are the usual bunch of fixes and cleanups.

  Specifics:

   - Add CSI-2 and DisCo for Imaging support to the ACPI device
     enumeration code (Sakari Ailus, Rafael J. Wysocki)

   - Adjust the cpufreq thermal reduction algorithm in the ACPI
     processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
     Bergmann)

   - Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki)

   - Switch over ACPI to using a threaded interrupt handler for the SCI
     (Rafael J. Wysocki)

   - Allow ACPI Notify () handlers to run on all CPUs and clean up the
     ACPI interface for deferred events processing (Rafael J. Wysocki)

   - Switch over the ACPI EC driver to using a threaded handler for the
     dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki)

   - Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock
     to keep local interrupts on (Rafael J. Wysocki)

   - Adjust the USB4 _OSC handshake to correctly handle cases in which
     certain types of OS control are denied by the platform (Mika
     Westerberg)

   - Correct and clean up the generic function for parsing ACPI
     data-only tables with array structure (Yuntao Wang)

   - Modify acpi_dev_uid_match() to support different types of its
     second argument and adjust its users accordingly (Raag Jadav)

   - Clean up code related to acpi_evaluate_reference() and ACPI device
     lists (Rafael J. Wysocki)

   - Use generic ACPI helpers for evaluating trip point temperature
     objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
     Bergmann)

   - Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
     zone driver (Jeff Brasen)

   - Modify the ACPI LPIT table handling code to avoid u32
     multiplication overflows in state residency computations (Nikita
     Kiryushin)

   - Drop an unused helper function from the ACPI backlight (video)
     driver and add a clarifying comment to it (Hans de Goede)

   - Update the ACPI backlight driver to avoid using uninitialized
     memory in some cases (Nikita Kiryushin)

   - Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo
     Qiu)

   - Add support for vendor-defined error types to the ACPI APEI error
     injection code (Avadhut Naik)

   - Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous
     memory failure events, so they are handled differently from the
     asynchronous ones (Shuai Xue)

   - Fix NULL pointer dereference check in the ACPI extlog driver
     (Prarit Bhargava)

   - Adjust the ACPI extlog driver to clear the Extended Error Log
     status when RAS_CEC handled the error (Tony Luck)

   - Add IRQ override quirks for some Infinity laptops and for TongFang
     GMxXGxx (David McFarland, Hans de Goede)

   - Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is
     not the same as one of the real pxm values (Yuntao Wang)

   - Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
     driver so as to prevent miscalculation of the values in the clock
     divider (Andy Shevchenko)

   - Adjust comments in the ACPI watchdog driver to prevent kernel-doc
     from complaining during documentation builds (Randy Dunlap)

   - Make the ACPI button driver send wakeup key events to user space in
     addition to power button events on systems that can be woken up by
     the power button (Ken Xue)

   - Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full
     structure field (Dmitry Antipov)"

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

To improve here there is a quest to make the remove callback return

2595665037 firmware: arm_scpi: 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 ignored (apart
from emitting a warning) and this typically results in resource leaks.

01638431c4 efi/x86: Fix the missing KASLR_FLAG bit in boot_params->hdr.loadflags 
When KASLR is enabled, the KASLR_FLAG bit in boot_params->hdr.loadflags
should be set to 1 to propagate KASLR status from compressed kernel to
kernel, just as the choose_random_location() function does.

Currently, when the kernel is booted via the EFI stub, the KASLR_FLAG
bit in boot_params->hdr.loadflags is not set, even though it should be.
This causes some functions, such as kernel_randomize_memory(), not to
execute as expected. Fix it.

Few minor updates:
 
 1. Addition of protocol versioning checks to warn if the firmware version
    is newer or greater than the version supported by the kernel driver
 
 2. Increment of the maximum OPP count in the perf protocol from 16 to 32
    as needed by a few recent/future qualcomm platforms
 
 3. Optimisation of set performance operations by returning error
    immediately and avoiding to send the command to the platform(which
    would return error eventually) if the domain doesn't support perf
    operations. Similarly, the fastchannel handling is also optimised by
    avoiding to initialise the corresponding set operations fastchannels.
 
 4. Extension of extended names helper to accomodate recently added new
    flags parameter to be able to properly configure the command used to
    query the extended name of a resource.

 support for PolarFire SoC. Auto Update is one of the ways that the FPGA
 bitstream can be updated, and the only one suitable for use from Linux
 as it does not immediately initiate a reboot when started.
 The driver was not accepted in the FPGA manager subsystem as the update
 only occurs after a reboot and makes no use of the FPGA manager
 framework.

8eb0b1ed65 Qualcomm driver updates for v6.8 
Support for SM8650 and X1E is added to the LLCC driver, the
 LLCC_TRP_ATTR2_CFGn register stride is corrected, and a bug where for
 each iteration looping over slices previous settings for dis_cap_alloc
 and retain_on_pc are overwritten.
 
 A quirk is introduced in UCSI, for implementations that does not handle
 UCSI_GET_PDOS for non-PD partners. With this, USCI support is enabled by
 default in pmic_glink. It is later reverted for SC8280XP due reported
 errors.
 
 A few memory leaks in error paths of qseecom are taken care of.
 
 A small driver to expose the ADSP PDCharger ULOG debug log is
 introduced, to aid debugging issues with pmic_glink.
 
 The identiy of SM8650, PM8937 and a few DSPs are added to the Qualcomm
 socinfo driver.
 
 The Qualcomm sleep stats driver is extended to allow getting detailed
 statistics about usage of various DDR states. Unfortunately this ABI
 does not seem to be stable across platforms, so this addition is dropped
 again while the reported problems are investigated further.
 
 Andy is moved from MAINTAINERS to CREDITS. Thank you, Andy.

Qualcomm driver updates for v6.8

Support for SM8650 and X1E is added to the LLCC driver, the
LLCC_TRP_ATTR2_CFGn register stride is corrected, and a bug where for
each iteration looping over slices previous settings for dis_cap_alloc
and retain_on_pc are overwritten.

A quirk is introduced in UCSI, for implementations that does not handle
UCSI_GET_PDOS for non-PD partners. With this, USCI support is enabled by
default in pmic_glink. It is later reverted for SC8280XP due reported
errors.

A few memory leaks in error paths of qseecom are taken care of.

A small driver to expose the ADSP PDCharger ULOG debug log is
introduced, to aid debugging issues with pmic_glink.

The identiy of SM8650, PM8937 and a few DSPs are added to the Qualcomm
socinfo driver.

The Qualcomm sleep stats driver is extended to allow getting detailed
statistics about usage of various DDR states. Unfortunately this ABI
does not seem to be stable across platforms, so this addition is dropped
again while the reported problems are investigated further.

Andy is moved from MAINTAINERS to CREDITS. Thank you, Andy.
