Merge tag 'drm-misc-next-2023-04-06' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v6.4-rc1:

UAPI Changes:

Cross-subsystem Changes:
- Document port and rotation dt bindings better.
- For panel timing DT bindings, document that vsync and hsync are
  first, rather than last in image.
- Fix video/aperture typos.

Core Changes:
- Reject prime DMA-Buf attachment if get_sg_table is missing.
  (For self-importing dma-buf only.)
- Add prime import/export to vram-helper.
- Fix oops in drm/vblank when init is not called.
- Fixup xres/yres_virtual and other fixes in fb helper.
- Improve SCDC debugs.
- Skip setting deadline on modesets.
- Assorted TTM fixes.

Driver Changes:
- Add lima usage stats.
- Assorted fixes to bridge/lt8192b, tc358767, ivpu,
  bridge/ti-sn65dsi83, ps8640.
- Use pci aperture helpers in drm/ast lynxfb, radeonfb.
- Revert some lima patches, as they required a commit that has been
  reverted upstream.
- Add AUO NE135FBM-N41 v8.1 eDP panel.
- Add QAIC accel driver.
