drm-misc-next for v6.7-rc1:
UAPI Changes:
- Nouveau changed to not set NO_PREFETCH flag explicitly.
Cross-subsystem Changes:
- Update documentation of dma-buf intro and uapi.
- fbdev/sbus fixes.
- Use initializer macros in a lot of fbdev drivers.
- Add Boris Brezillon as Panfrost driver maintainer.
- Add Jessica Zhang as drm/panel reviewer.
- Make more fbdev drivers use fb_ops helpers for deferred io.
- Small hid trailing whitespace fix.
- Use fb_ops in hid/picolcd
Core Changes:
- Assorted small fixes to ttm tests, drm/mst.
- Documentation updates to bridge.
- Add kunit tests for some drm_fb functions.
- Rework drm_debugfs implementation.
- Update xe documentation to mark todos as completed.
Driver Changes:
