Merge tag 'drm-misc-next-2025-11-05-1' of https://gitlab.freedesktop.org/drm/misc/kernel into drm-next

drm-misc-next for v6.19-rc1:

UAPI Changes:
- Add userptr support to ivpu.
- Add IOCTL's for resource and telemetry data in amdxdna.

Core Changes:
- Improve some atomic state checking handling.
- drm/client updates.
- Use forward declarations instead of including drm_print.h
- RUse allocation flags in ttm_pool/device_init and allow specifying max
  useful pool size and propagate ENOSPC.
- Updates and fixes to scheduler and bridge code.
- Add support for quirking DisplayID checksum errors.

Driver Changes:
- Assorted cleanups and fixes in rcar-du, accel/ivpu, panel/nv3052cf,
  sti, imxm, accel/qaic, accel/amdxdna, imagination, tidss, sti,
  panthor, vkms.
- Add Samsung S6E3FC2X01 DDIC/AMS641RW, Synaptics TDDI series DSI,
  TL121BVMS07-00 (IL79900A) panels.
- Add mali MediaTek MT8196 SoC gpu support.
- Add etnaviv GC8000 Nano Ultra VIP r6205 support.
- Document powervr ge7800 support in the devicetree.
