Merge tag 'drm-intel-next-2024-06-28' of https://gitlab.freedesktop.org/drm/i915/kernel into drm-next

drm/i915 feature pull #2 for v6.11:

Features and functionality:
- More eDP Panel Replay enabling (Jouni)
- Add async flip and flip done tracepoints (Ville)

Refactoring and cleanups:
- Clean up BDW+ pipe interrupt register definitions (Ville)
- Prep work for DSB based plane programming (Ville)
- Relocate encoder suspend/shutdown helpers (Imre)
- Polish plane surface alignment handling (Ville)

Fixes:
- Enable more fault interrupts on TGL+/MTL+ (Ville)
- Fix CMRR 32-bit build (Mitul)
- Fix PSR Selective Update Region Scan Line Capture Indication (Jouni)
- Fix cursor fb unpinning (Maarten, Ville)
- Fix Cx0 PHY PLL state verification in TBT mode (Imre)
- Fix unnecessary MG DP programming on MTL+ Type-C (Imre)

DRM changes:
- Rename drm_plane_check_pixel_format() to drm_plane_has_format() and export
  (Ville)
- Add drm_vblank_work_flush_all() (Maarten)

Xe driver changes:
- Call encoder .suspend_complete() hook also on Xe (Imre)
