Merge tag 'drm-misc-next-2024-09-20' of https://gitlab.freedesktop.org/drm/misc/kernel into drm-next

drm-misc-next for v6.12:

UAPI Changes:
- Add panthor/DEV_QUERY_TIMESTAMP_INFO query.

Cross-subsystem Changes:
- Updated dt bindings.
- Add documentation explaining default errnos for fences.
- Mark dma-buf heaps creation functions as __init.

Core Changes:
- Split DSC helpers from DP helpers.
- Clang build fixes for drm/mm test.
- Remove simple pipeline support for gem-vram,
  no longer any users left after converting bochs.
- Add erno to drm_sched_start to distinguish between GPU and queue
  reset.
- Add drm_framebuffer testcases.
- Fix uninitialized spinlock acquisition with CONFIG_DRM_PANIC=n.
- Use read_trylock instead of read_lock in dma_fence_begin_signalling to
  quiesce lockdep.

Driver Changes:
- Assorted small fixes and updates for tegra, host1x, imagination,
  nouveau, panfrost, panthor, panel/ili9341, mali, exynos,
  panel/samsung-s6e3fa7, ast, bridge/ti-sn65dsi86, panel/himax-hx83112a,
  bridge/tc358767, bridge/imx8mp-hdmi-tx, panel/khadas-ts050,
  panel/nt36523, panel/sony-acx565akm, kmb, accel/qaic, omap, v3d.
- Add bridge/TI TDP158.
- Assorted documentation updates.
- Convert bochs from simple drm to gem shmem, and check modes
  against available memory.
- Many VC4 fixes, most related to scaling and YUV support.
- Convert some drivers to use SYSTEM_SLEEP_PM_OPS and RUNTIME_PM_OPS.
- Rockchip 4k@60 support.
