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.

Commit c14e64b46944 ("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 73380e2573c3 ("soc: qcom: stats: fix 64-bit division")
Commit e84e61bdb97c ("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.

Environment firmware interface to access EFI variables on certain
devices, and new features for multiple platform and firmware
drivers.
- Arm FF-A firmware support gains support for v1.1 specification
features, in particular notification and memory transaction
descriptor changes.
- SCMI firmware support now support v3.2 features for clock and DVFS
configuration and a new transport for Qualcomm platforms.
- Minor cleanups and bugfixes are added to pretty much all the active
platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive,
amlogic, atmel, tegra, aspeed, vexpress, mediatek, samsung and
more.
In particular, this contains portions of the treewide conversion to
use __counted_by annotations and the device_get_match_data helper"

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 via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.
This code was found with the help of Coccinelle, and audited and
fixed manually.

As it was pointed out by Simon Ser, the DRM_MODE_CONNECTOR_USB connector
is reserved for the GUD devices. Other drivers (i915, amdgpu) use
DRM_MODE_CONNECTOR_DisplayPort even if the DP stream is handled by the
USB-C altmode. While we are still working on implementing the proper way
to let userspace know that the DP is wrapped into USB-C, change
connector type to be DRM_MODE_CONNECTOR_DisplayPort.

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.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

In some configurations, the exact placement of the rmtfs shared memory
region isn't so strict. The DeviceTree author can then choose to use the
"size" property and rely on the OS for placement (in combination with
"alloc-ranges", if desired).
But on some platforms the rmtfs memory region may not be allocated
adjacent to regions allocated by other clients. Add support for
discarding the first and last 4k block in the region, if
qcom,use-guard-pages is specified in DeviceTree.
