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.

+DRM_IOCTL_QAIC_DETACH_SLICE_BO
+  This IOCTL allows userspace to remove the slicing information from a BO that
+  was originally provided by a call to DRM_IOCTL_QAIC_ATTACH_SLICE_BO. This
+  is the inverse of DRM_IOCTL_QAIC_ATTACH_SLICE_BO. The BO must be idle for
+  DRM_IOCTL_QAIC_DETACH_SLICE_BO to be called. After a successful detach slice
+  operation the BO may have new slicing information attached with a new call
+  to DRM_IOCTL_QAIC_ATTACH_SLICE_BO. After detach slice, the BO cannot be
+  executed until after a new attach slice operation. Combining attach slice
+  and detach slice calls allows userspace to use a BO with multiple workloads.
