- Preparation and changes for upcoming
  XeLPD display IP (Jose, Matt, Ville, Juha-Pekka, Animesh).
- Fix comment typo in DSI code (zuoqilin).
- Simplify CCS and UV plane alignment handling (Imre).
- PSR Fixes on TGL (Gwan-gyeong, Jose).

- Use unique backlight device names (Jani).
- A few clean-ups on i915/audio (Jani).
- Use intel_framebuffer instead of drm one on intel_fb functions (Imre).
- Add the missing MC CCS/XYUV8888 format support on display >= 12 (Imre).
- Nuke display error state (Ville).
- ADL-P initial enablement patches
  starting to land (Clint, Imre, Jose, Umesh, Vandita, Mika).
- Display clean-up around VBT and the strap bits (Lucas).
- Try YCbCr420 color when RGB fails (Werner).
