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. 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 (17): drm/i915/psr: Store pr_dpcd in intel_dp drm/panel replay: Add edp1.5 Panel Replay bits and register drm/i915/psr: Move printing sink PSR support to own function drm/i915/psr: Move printing PSR mode to own function drm/i915/psr: modify psr status debugfs to support eDP Panel Replay drm/i915/psr: Add Panel Replay support to intel_psr2_config_et_valid drm/i915/psr: Add Early Transport into psr debugfs interface drm/display: Add missing aux less alpm wake related bits 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: Check Early Transport for Panel Replay as well drm/i915/psr: Modify dg2_activate_panel_replay to support eDP drm/i915/psr: Add new debug bit to disable Panel Replay Revert "drm/i915/psr: Disable early transport by default" .../drm/i915/display/intel_display_types.h | 2 + drivers/gpu/drm/i915/display/intel_psr.c | 294 ++++++++++++------ include/drm/display/drm_dp.h | 19 +- 3 files changed, 213 insertions(+), 102 deletions(-)
