Merge tag 'drm-misc-next-2023-03-23' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v6.4-rc1:
Core Changes:
- Add unit test for xrgb8888 to mono.
- Assorted small fixes to format helper selftests.
- Assorted documentation updates.
- Drop drm_dev_set_unique.
- Always use shadow buffer in generic fbdev emulation helpers, and
improve error handling.
Driver Changes:
- Assorted small fixes to malidp, hdlcd, gma500, lima, bridge, rockchip.
- Move fbdev in gma500 to use drm_client.
- Convert bridge platform callbacks to void return.
- Drop leftover from vgem to shmem helper conversion.
