Merge tag 'drm-intel-next-2025-06-18' of https://gitlab.freedesktop.org/drm/i915/kernel into drm-next
drm/i915 feature pull for v6.17:
Features and functionality:
- Add support for DSC fractional link bpp on DP MST (Imre)
- Add support for simultaneous Panel Replay and Adaptive Sync (Jouni)
- Add support for PTL+ double buffered LUT registers (Chaitanya, Ville)
- Add PIPEDMC event handling in preparation for flip queue (Ville)
Refactoring and cleanups:
- Rename lots of DPLL interfaces to unify them (Suraj)
- Allocate struct intel_display dynamically (Jani)
- Abstract VLV IOSF sideband better (Jani)
- Use str_true_false() helper (Yumeng Fang)
- Refactor DSB code in preparation for flip queue (Ville)
- Use drm_modeset_lock_assert_held() instead of open coding (Luca)
- Remove unused arg from skl_scaler_get_filter_select() (Luca)
- Split out a separate display register header (Jani)
- Abstract DRAM detection better (Jani)
- Convert LPT/WPT SBI sideband to struct intel_display (Jani)
Fixes:
- Fix DSI HS command dispatch with forced pipeline flush (Gareth Yu)
- Fix BMG and LNL+ DP adaptive sync SDP programming (Ankit)
- Fix error path for xe display workqueue allocation (Haoxiang Li)
- Disable DP AUX access probe where not required (Imre)
- Fix DKL PHY access if the port is invalid (Luca)
- Fix PSR2_SU_STATUS access on ADL+ (Jouni)
- Add sanity checks for porch and sync on BXT/GLK DSI (Ville)
DRM core changes:
- Change AUX DPCD access probe address (Imre)
- Refactor EDID quirks, amd make them available to drivers (Imre)
- Add quirk for DPCD access probe (Imre)
- Add DPCD definitions for Panel Replay capabilities (Jouni)
Merges:
- Backmerges to sync with v6.15-rcs and v6.16-rc1 (Jani)
