Panel Replay is a power saving feature for DP 2.0 monitor and similar to PSR on EDP. These patches are basic enablement patches added on top of existing psr framework to enable full-screen live active frame update mode of panel replay. Panel replay also can be enabled in selective update mode which will be enabled in a incremental approach. As per current design panel replay priority is higher than psr. intel_dp->psr.pr_enabled flag indicate panel replay is enabled. intel_dp->psr.pr_enabled + intel_dp->psr.psr2_enabled indicates panel replay is enabled in selective update mode. intel_dp->psr.pr_enabled + intel_dp->psr.psr2_enabled + intel_psr.selective_fetch enabled indicates panel replay is enabled in selective update mode with selective fetch. PSR replated flags remain same like before. Note: The patches are not tested due to unavailability of monitor.
