Merge tag 'drm-misc-next-2023-09-27' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v6.7-rc1:
UAPI Changes:
- drm_file owner is now updated during use, in the case of a drm fd
opened by the display server for a client, the correct owner is
displayed.
- Qaic gains support for the QAIC_DETACH_SLICE_BO ioctl to allow bo
recycling.
Cross-subsystem Changes:
- Disable boot logo for au1200fb, mmpfb and unexport logo helpers.
Only fbcon should manage display of logo.
- Update freescale in MAINTAINERS.
- Add some bridge files to bridge in MAINTAINERS.
- Update gma500 driver repo in MAINTAINERS to point to drm-misc.
Core Changes:
- Move size computations to drm buddy allocator.
- Make drm_atomic_helper_shutdown(NULL) a nop.
- Assorted small fixes in drm_debugfs, DP-MST payload addition error handling.
- Fix DRM_BRIDGE_ATTACH_NO_CONNECTOR handling.
- Handle bad (h/v)sync_end in EDID by clipping to htotal.
- Build GPUVM as a module.
Driver Changes:
- Simple drivers don't need to cache prepared result.
- Call drm_atomic_helper_shutdown() in shutdown/unbind for a whole lot
more drm drivers.
- Assorted small fixes in amdgpu, ssd130x, bridge/it6621, accel/qaic,
nouveau, tc358768.
- Add NV12 for komeda writeback.
- Add arbitration lost event to synopsis/dw-hdmi-cec.
- Speed up s/r in nouveau by not restoring some big bo's.
- Assorted nouveau display rework in preparation for GSP-RM,
especially related to how the modeset sequence works and
the DP sequence in relation to link training.
- Update anx7816 panel.
- Support NVSYNC and NHSYNC in tegra.
- Allow multiple power domains in simple driver.
