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.
v7:
- fix improper SU area width
- writing wrong register in Wa 16021440873
- disable Panel Replay if psr_enable is set != -1
- perfrom ALPM check for Panel Replay Full Frame update
- printout why Panel Replay is disabled
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
- printout debug info in case Panel Replay is prevented
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
