Pull drm updates from Dave Airlie:
 "This contains two major new drivers:

   - imagination is a first driver for Imagination Technologies devices,
     it only covers very specific devices, but there is hope to grow it

   - xe is a reboot of the i915 GPU (shares display) side using a more
     upstream focused development model, and trying to maximise code
     sharing. It's not enabled for any hw by default, and will hopefully
     get switched on for Intel's Lunarlake.

  This also drops a bunch of the old UMS ioctls. It's been dead long
  enough.

  amdgpu has a bunch of new color management code that is being used in
  the Steam Deck.

  amdgpu also has a new ACPI WBRF interaction to help avoid radio
  interference.

6db359b5ee soc: pxa: ssp: fix casts
On ARM64 platforms, id->data is a 64-bit value and casting it to a
32-bit integer causes build errors. Cast it to uintptr_t instead.

The id->driver_data cast is unnecessary, so drop it.

97d62760e4 drivers: soc: xilinx: add check for platform
Some error event IDs for Versal and Versal NET are different.
Both the platforms should access their respective error event
IDs so use sub_family_code to check for platform and check
error IDs for respective platforms. The family code is passed
via platform data to avoid platform detection again.
Platform data is setup when even driver is registered.

RISC-V cache drivers for v6.8

The SiFive composable cache driver moves to the cache driver
subdirectory from the drivers/soc and grows support for non-coherent
cache operations. The immediate user for these is the jh7100 SoC, that
a rake of people have on VisionFive v1 or Beagle-V Starlight boards.

RISC-V SoC drivers for v6.8

There's only one set of changes here, the addition of "Auto Update"
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.

Samsung SoC driver changes for v6.8

1. Add support for Google GS101 SoC to different drivers: clock
   controller, serial and watchdog.

   The clock driver changes depend on few bindings headers, which I put
   in a topic branch with the bindings refactoring and GS101 support,
   therefore this this pull request includes that bindings topic branch.

   The rest of the bindings topic branch is not necessary here, however
   keeping everything together makes it easier to share between
   branches.  The bindings topic branch is mostly refactoring all the
   compatibles to add SoC-specific compatible followed by fallback.

2. Exynos ChipID: recognize ExynosAutov920.

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.

eed6e57e9f soc: qcom: llcc: Fix dis_cap_alloc and retain_on_pc configuration
Commit c14e64b469 ("soc: qcom: llcc: Support chipsets that can
 write to llcc") add the support for chipset where capacity based
allocation and retention through power collapse can be programmed
based on content of SCT table mentioned in the llcc driver where
the target like sdm845 where the entire programming related to it
is controlled in firmware. However, the commit introduces a bug
where capacity/retention register get overwritten each time it
gets programmed for each slice and that results in misconfiguration
of the register based on SCT table and that is not expected
behaviour instead it should be read modify write to retain the
configuration of other slices.

This issue is totally caught from code review and programming test
and not through any power/perf numbers so, it is not known what
impact this could make if we don't have this change however,
this feature are for these targets and they should have been
programmed accordingly as per their configuration mentioned in
SCT table like others bits information.

This change brings one difference where it keeps capacity/retention
bits of the slices that are not mentioned in SCT table in unknown
state where as earlier it was initialized to zero.

Commit 73380e2573 ("soc: qcom: stats: fix 64-bit division")
Commit e84e61bdb9 ("soc: qcom: stats: Add DDR sleep stats")

The feature itself is rather useful for debugging DRAM power management,
however it looks like the shared RPMh stats data structures differ on
previous SoCs.

Revert its addition for now to un-break booting on these earlier SoCs,
while I try to come up with a better way to enable it conditionally.

b1891c1364 soc: fsl: cpm1: qmc: Remove no more needed checks from qmc_check_chans()
The newly introduced qmc_chan_setup_tsa* functions check that the
channel entries are not already used.
These checks are also performed by qmc_check_chans() and are no more
needed.

Remove them from qmc_check_chans().

9b7a69d0bd soc: fsl: cpm1: qmc: Introduce available timeslots masks
Available timeslots masks define timeslots available for the related
channel. These timeslots are defined by the QMC binding.

Timeslots used are initialized to available timeslots but can be a
subset of available timeslots.
This prepares the dynamic timeslots management (ie. changing timeslots
at runtime).

0e034aec5b soc: fsl: cpm1: qmc: Extend the API to provide Rx status
In HDLC mode, some status flags related to the data read transfer can be
set by the hardware and need to be known by a QMC consumer for further
analysis.

Extend the API in order to provide these transfer status flags at the
read complete() call.

In TRANSPARENT mode, these flags have no meaning. Keep only one read
complete() API and update the consumers working in transparent mode.
In this case, the newly introduced flags parameter is simply unused.

The qmc_chan_reset_rx() set the is_rx_stopped flag. This leads to an
inconsistent state in the following sequence.
    qmc_chan_stop()
    qmc_chan_reset()
Indeed, after the qmc_chan_reset() call, the channel must still be
stopped. Only a qmc_chan_start() call can move the channel from stopped
state to started state.

Fix the issue removing the is_rx_stopped flag setting from
qmc_chan_reset()

Some members of struct svs_bank are not changed during runtime, so those
are not variables but constants: move all of those to a new structure
called svs_bank_pdata and refactor the code to make use of that and
reorder members by size where possible.
This effectively moves at least 50 bytes to the text segment.
While at it, also uniform the thermal zone names across the banks.

INIT01 and INIT02 modes are available - but that's done in for loops and
for each SVS bank.

Give those a shortcut to get out early if no SVS bank features the
desired init mode: this is especially done to avoid some locking in
the svs_init01(), but also to avoid multiple for loops to check the
same, when no bank supports a specific mode.
