Merge tag 'drm-misc-next-2022-08-20-1' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v6.1:

UAPI Changes:

Cross-subsystem Changes:
- DMA-buf: documentation updates.
- Assorted small fixes to vga16fb
- Fix fbdev drivers to use the aperture helpers.
- Make removal of conflicting drivers work correctly without fbdev enabled.

Core Changes:
- bridge, scheduler, dp-mst: Assorted small fixes.
- Add more format helpers to fourcc, and use it to replace the cpp usage.
- Add DRM_FORMAT_Cxx, DRM_FORMAT_Rxx (single channel), and DRM_FORMAT_Dxx
  ("darkness", inverted single channel)
- Add packed AYUV8888 and XYUV8888 formats.
- Assorted documentation updates.
- Rename ttm_bo_init to ttm_bo_init_validate.
- Allow TTM bo's to exist without backing store.
- Convert drm selftests to kunit.
- Add managed init functions for (panel) bridge, crtc, encoder and connector.
- Fix endianness handling in various format conversion helpers.
- Make tests pass on big-endian platforms, and add test for rgb888 -> rgb565
- Move DRM_PLANE_HELPER_NO_SCALING to atomic helpers and rename, so
  drm_plane_helper is no longer needed in most drivers.
- Use idr_init_base instead of idr_init.
- Rename FB and GEM CMA helpers to DMA helpers.
- Rework XRGB8888 related conversion helpers, and add drm_fb_blit() that
  takes a iosys_map. Make drm_fb_memcpy take an iosys_map too.
- Move edid luminance calculation to core, and use it in i915.

Driver Changes:
- bridge/{adv7511,ti-sn65dsi86,parade-ps8640}, panel/{simple,nt35510,tc358767},
  nouveau, sun4i, mipi-dsi, mgag200, bochs, arm, komeda, vmwgfx, pl111:
  Assorted small fixes and doc updates.
- vc4: Rework hdmi power up, and depend on PM.
- panel/simple: Add Samsung LTL101AL01.
- ingenic: Add JZ4760(B) support, avoid a modeset when sharpness property
  is unchanged, and use the new PM ops.
- Revert some amdgpu commits that cause garbaged graphics when starting
  X, and reapply them with the real problem fixed.
- Completely rework vc4 init to use managed helpers.
- Rename via_drv to via_dri1, and move all stuff there only used by the
  dri1 implementation in preperation for atomic modeset.
- Use regmap bulk write in ssd130x.
- Power sequence and clock updates to it6505.
- Split panel-sitrox-st7701  init sequence and rework mode programming code.
- virtio: Improve error and edge conditions handling, and convert to use managed
  helpers.
- Add Samsung LTL101AL01, B120XAN01.0, R140NWF5 RH, DMT028VGHMCMI-1A T, panels.
- Add generic fbdev support to komeda.
- Split mgag200 modeset handling to make it more model-specific.
- Convert simpledrm to use atomic helpers.
- Improve udl suspend/disconnect handling.
