Merge tag 'drm-next-2024-05-15' of https://gitlab.freedesktop.org/drm/kernel

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 ttm: - improve placement for TTM BOs in idle/busy handling panic: - Fixes for drm-panic, and option to test it. - Add drm panic to simpledrm, mgag200, imx, ast bridge: - improve init ordering - adv7511: allow GPIO pin sharing - tc358775: add tc358675 support panel: - AUO B120XAN01.0 - Samsung s6e3fa7 - BOE NT116WHM-N44 -
