Merge tag 'drm-misc-next-2022-03-03' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v5.18:

UAPI Changes:

Cross-subsystem Changes:
- Improve performance of some fbdev ops, in some cases up to 6x faster.

Core Changes:
- Some small DP fixes.
- Find panels in subnodes of OF devices, and add of_get_drm_panel_display_mode
  to retrieve mode.
- Add drm_object_property_get_default_value and use it for resetting
  zpos in plane state reset, removing the need for individual drivers
  to do it.
- Same for color encoding and color range props.
- Update panic handling todo doc.
- Add todo that format conversion helpers should be sped up similarly to fbdev ops.

Driver Changes:
- Add panel orientation property to simpledrm for quirked panels.
- Assorted small fixes to tiny/repaper, nouveau, stm, omap, ssd130x.
- Add crc support to stm/ltdc.
- Add MIPI DBI compatible SPI driver
- Assorted small fixes to tiny panels and bridge drivers.
- Add AST2600 support to aspeed.
