[PATCH v4 00/19] Panel Replay eDP support

[Jouni Högander]

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.

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 (19):
