[PATCH v6 00/26] Panel Replay eDP support

[Jouni Högander]

This patch set is implementing eDP1.5 Panel Replay for Intel hw. Patch
to disable Region Early Transport by default is reverted as it is
needed by eDP Panel Replay.

Patches 1 - 14 are fixes and clean-ups for DP2.0 Panel Replay found while testing with eDP1.5 panel. Patches 15 - 26 are implementing Panel Replay eDP.

v6:
  - fix and rework sink enable
  - rework checking vblank length for LunarLake and Panel Replay
  - reorder patches
v5:
  - use psr->su_region_et_enabled instead of psr2_su_region_et_valid
  - do not check Vblank >= PSR2_CTL Block Count Number for Panel Replay
v4:
  - add some patch from "Panel Replay fixes" set here
  - check 128b/132b encoding and HDCP enable
  - use intel_alpm_aux_wake_supported instead of local variable
v3:
  - commit message modifications
  - s/intel_psr_psr_mode/intel_psr_print_mode/
  - remove extra space from "PSR mode:  disabled"
  - do not allow eDP Panel Replay when using 128b/132b encoding
  - do not allow eDP Panel Replay when HDCP is enabled
v2:
  - printout "Selective Update enabled (Early Transport)" instead of
    "Selective Update Early Transport enabled"
  - ensure that fastset is performed when the disable bit changes

Jouni Högander (26):
  drm/i915/alpm: Do not use fast_wake_lines for aux less wake time
  drm/i915/alpm: Write also AUX Less Wake lines into ALPM_CTL
  drm/i915/display: Take panel replay into account in vsc sdp unpacking
  drm/i915/display: Skip Panel Replay on pipe comparison if no active
    planes
  drm/display: Add missing Panel Replay Enable SU Region ET bit
  drm/i915/psr: Split enabling sink for PSR and Panel Replay
  drm/i915/alpm: Make alpm support checks non-static

    variable
  drm/i915/psr: Add Panel Replay support to intel_psr2_config_et_valid
  drm/i915/psr: Print Panel Replay status instead of frame lock status
  drm/i915/psr: Move vblank length check to separate function

  dmr/i915/psr: Wake time is aux less wake time for Panel Replay
  drm/i915/psr: Check panel ALPM capability for eDP Panel Replay
  drm/i915/psr: Inform Panel Replay source support on eDP as well
  drm/i915/psr: enable sink for eDP1.5 Panel Replay
  drm/i915/psr: Check panel Early Transport capability for eDP PR
  drm/i915/psr: Perfrom psr2 checks related to ALPM for Panel Replay
  drm/i915/psr: Add Panel Replay compute_config helper
  drm/i915/psr: 128b/132b Panel Replay is not supported on eDP
  drm/i915/psr: HW will not allow PR on eDP when HDCP enabled
  drm/i915/psr: Check Early Transport for Panel Replay as well
  drm/i915/psr: Modify dg2_activate_panel_replay to support eDP
