[v3,00/20] Panel Replay eDP support

Message

Hogander, Jouni May 27, 2024, 7:22 a.m. UTC

This patch set is implementing eDP1.5 Panel Replay for Intel hw. Also
Region Early Transport information is added into debugfs interface
and patch to disable Region Early Transport by default is reverted as
it is needed by eDP Panel Replay.

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
