Merge tag 'drm-misc-next-2023-03-07' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v6.4-rc1:
Note: Only changes since pull request from 2023-02-23 are included here.
UAPI Changes:
- Convert rockchip bindings to YAML.
- Constify kobj_type structure in dma-buf.
- FBDEV cmdline parser fixes, and other small fbdev fixes for mode
parsing.
Cross-subsystem Changes:
- Add Neil Armstrong as linaro maintainer.
- Actually signal the private stub dma-fence.
Core Changes:
- Add function for adding syncobj dep to sched_job and use it in panfrost, v3d.
- Improve DisplayID 2.0 topology parsing and EDID parsing in general.
- Add a gem eviction function and callback for generic GEM shrinker
purposes.
- Prepare to convert shmem helper to use the GEM reservation lock instead of own
locking. (Actual commit itself got reverted for now)
- Move the suballocator from radeon and amdgpu drivers to core in preparation
for Xe.
- Assorted small fixes and documentation.
- Fixes to HPD polling.
- Assorted small fixes in simpledrm, bridge, accel, shmem-helper,
and the selftest of format-helper.
- Remove dummy resource when ttm bo is created, and during pipelined
gutting. Fix all drivers to accept a NULL ttm_bo->resource.
- Handle pinned BO moving prevention in ttm core.
- Set drm panel-bridge orientation before connector is registered.
- Remove dumb_destroy callback.
- Add documentation to GEM_CLOSE, PRIME_HANDLE_TO_FD, PRIME_FD_TO_HANDLE, GETFB2 ioctl's.
- Add atomic enable_plane callback, use it in ast, mgag200, tidss.
Driver Changes:
- Use drm_gem_objects_lookup in vc4.
- Assorted small fixes to virtio, ast, bridge/tc358762, meson, nouveau.
- Allow virtio KMS to be disabled and compiled out.
- Add Radxa 8/10HD, Samsung AMS495QA01 panels.
- Fix ivpu compiler errors.
- Assorted fixes to drm/panel, malidp, rockchip, ivpu, amdgpu, vgem,
nouveau, vc4.
- Assorted cleanups, simplifications and fixes to vmwgfx.
