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.

  Otherwise it's the usual lots of changes in lots of places.

<title>drm/vc4: tests: Use KUNIT_DEFINE_ACTION_WRAPPER</title>

In order to pass functions to kunit_add_action(), they need to be of the
kunit_action_t type. While casting the function pointer can work, it
will break control-flow integrity.

vc4_mock already defines such a wrapper for drm_dev_unregister(), but it
involves less boilerplate to use the new macro, so replace the manual
implementation.

Even though we were rolling our own custom state for the vc4 HDMI
controller driver, we were still using the generic helper to destroy
that state.

It was mostly working since the underlying state is the first member of
our state so the pointers are probably equal in all relevant cases, but
it's still fragile so let's fix this properly.

wasn't any real conflict.]

The VC4 mock helpers allocate the CRTC, encoders and connectors using a
call to kunit_kzalloc(), but the DRM device they are attache to survives
for longer than the test itself which leads to use-after-frees reported
by KASAN.

Switch to drmm_kzalloc to tie the lifetime of these objects to the main
DRM device.

The VC4 mock helpers allocate the CRTC, encoders and connectors using a
call to kunit_kzalloc(), but the DRM device they are attache to survives
for longer than the test itself which leads to use-after-frees reported
by KASAN.

Switch to drmm_kzalloc to tie the lifetime of these objects to the main
DRM device.

<title>drm/vc4: Annotate struct vc4_perfmon with __counted_by</title>

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct vc4_perfmon.

drm-misc-next for v6.7-rc1:

UAPI Changes:
- drm_file owner is now updated during use, in the case of a drm fd
  opened by the display server for a client, the correct owner is
  displayed.
- Qaic gains support for the QAIC_DETACH_SLICE_BO ioctl to allow bo
  recycling.

Cross-subsystem Changes:
- Disable boot logo for au1200fb, mmpfb and unexport logo helpers.
  Only fbcon should manage display of logo.
- Update freescale in MAINTAINERS.
- Add some bridge files to bridge in MAINTAINERS.
- Update gma500 driver repo in MAINTAINERS to point to drm-misc.

Core Changes:
- Move size computations to drm buddy allocator.
- Make drm_atomic_helper_shutdown(NULL) a nop.
- Assorted small fixes in drm_debugfs, DP-MST payload addition error handling.
- Fix DRM_BRIDGE_ATTACH_NO_CONNECTOR handling.
- Handle bad (h/v)sync_end in EDID by clipping to htotal.
- Build GPUVM as a module.

Driver Changes:
- Simple drivers don't need to cache prepared result.
- Call drm_atomic_helper_shutdown() in shutdown/unbind for a whole lot
  more drm drivers.
- Assorted small fixes in amdgpu, ssd130x, bridge/it6621, accel/qaic,
  nouveau, tc358768.
- Add NV12 for komeda writeback.
- Add arbitration lost event to synopsis/dw-hdmi-cec.
- Speed up s/r in nouveau by not restoring some big bo's.
- Assorted nouveau display rework in preparation for GSP-RM,
  especially related to how the modeset sequence works and
  the DP sequence in relation to link training.
- Update anx7816 panel.
- Support NVSYNC and NHSYNC in tegra.
- Allow multiple power domains in simple driver.

<title>drm/vc4: Call drm_atomic_helper_shutdown() at shutdown time</title>

Based on grepping through the source code these drivers appear to be
missing a call to drm_atomic_helper_shutdown() at system shutdown
time. Among other things, this means that if a panel is in use that it
won't be cleanly powered off at system shutdown time.

The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart comes straight out of the kernel doc "driver
instance overview" in drm_drv.c.
