Pull drm updates from Dave Airlie:
"This is the main pull request for the drm subsystems for 6.10.
In drivers the main thing is a new driver for ARM Mali firmware based
GPUs, otherwise there are a lot of changes to amdgpu/xe/i915/msm and
scattered changes to everything else.
In the core a bunch of headers and Kconfig was refactored, along with
the addition of a new panic handler which is meant to provide a user
friendly message when a panic happens and graphical display is
enabled.
New drivers:
- panthor: ARM Mali/Immortalis CSF-based GPU driver
Core:
- add a CONFIG_DRM_WERROR option
- make more headers self-contained
- grab resv lock in pin/unpin
- fix vmap resv locking
- EDID/eDP panel matching
- Kconfig cleanups
- DT sound bindings
- Add SIZE_HINTS property for cursor planes
- Add struct drm_edid_product_id and helpers.
- Use drm device based logging in more drm functions.
- drop seq_file.h from a bunch of places
- use drm_edid driver conversions
dp:
- DP Tunnel documentation
- MST read sideband cap
- Adaptive sync SDP prep work
