Merge tag 'drm-intel-next-2025-11-14' of https://gitlab.freedesktop.org/drm/i915/kernel into drm-next
drm/i915 feature pull #2 for v6.19:
Features and functionality:
- Add initial display support for Xe3p_LPD, display version 35 (Sai Teja, Matt
R, Gustavo, Matt A, Ankit, Juha-pekka, Luca, Ravi Kumar)
- Compute LT PHY HDMI params when port clock not in predefined tables (Suraj)
Refactoring and cleanups:
- Refactor intel_frontbuffer split between i915, xe, and display (Ville)
- Clean up intel_de_wait_custom() usage (Ville)
- Unify display register polling interfaces (Ville)
- Finish removal of the expensive format info lookups (Ville)
- Cursor code cleanups (Ville)
- Convert intel_rom interfaces to struct drm_device (Jani)
Fixes:
- Fix uninitialized variable in DSI exec packet (Jonathan)
- Fix PIPEDMC logging (Alok Tiwari)
- Fix PSR pipe to vblank conversion (Jani)
- Fix intel_frontbuffer lifetime handling (Ville)
- Disable Panel Replay on DP MST for the time being (Imre)
Merges:
- Backmerge drm-next to get the drm_print.h changes (Jani)
