[PATCH v5 0/8] drm/i915/display: Add initial support for Xe3p_LPD

[Gustavo Sousa <gustavo.sousa@intel.com>]

This series adds initial support for Xe3p_LPD, Intel's display
architecture with IP version 35.

This series contains basic enabling patches and does not provide
complete support for the display IP yet. More involved features, like
the new PHY implementation and ALPM are implemented as separate patch
series.

Changes in v5:
- Dropped patch "drm/i915/wm: Do not make latency values monotonic on
  Xe3 onward", as it needs a bit more discussion and is not critical for
  this series.
- Dropped patch "drm/i915/xe3p_lpd: Extend Type-C flow for static DDI
  allocation".  I'll send it as a standalone patch.
- Incorporated review feedback for the other patches. Please check the
  changelog in the individual patches for details.
- Link to v4: https://patch.msgid.link/20251107-xe3p_lpd-basic-enabling-v4-0-ab3367f65f15@intel.com

Changes in v4:
- Skipped patches from v3 that were already applied.
- Dropped patch "drm/i915/xe3p_lpd: Enable system caching for FBC" with
  the expectation that its next version will be sent as a standalone
  patch.
- Link to v3: https://patch.msgid.link/20251103-xe3p_lpd-basic-enabling-v3-0-00e87b510ae7@intel.com

Changes in v3:
- Reshuffled patches so that most of the ones already containing a r-b
  are placed at the start.
- Dropped "drm/i915/xe3p_lpd: Wait for AUX channel power status", as a
  similar patch was already applied from a patch series dedicated to LT
  PHY
  (https://lore.kernel.org/all/20251101032513.4171255-25-suraj.kandpal@intel.com/).
- Dropped patches related to UINT16 plane formats, as they were
  incomplete and were not specific to Xe3p_LPD.
- Dropped FBC related patches, as Vinod is handling them as a separated
  series
  (https://lore.kernel.org/intel-gfx/20251027134001.325064-1-vinod.govindapillai@intel.com/)
- Dropped "drm/i915/xe3p_lpd: PSR SU minimum lines is 4", since that
  change is not valid according to Bspec.
- Incorporated review feedback on the other patches. Please check the
  changelog in the individual patches for details.
- Link to v2: https://lore.kernel.org/r/20251021-xe3p_lpd-basic-enabling-v2-0-10eae6d655b8@intel.com

Changes in v2:
- Incorporated review feedback. Please check the changelog in the
  patches for details.
- Link to v1: https://lore.kernel.org/r/20251015-xe3p_lpd-basic-enabling-v1-0-d2d1e26520aa@intel.com
