This series fixes issues faced when HDMI2.1 sink connected via HDMI2.1 PCON does not support DSC, and other minor HDMI2.1 PCON fixes/refactoring. Patch 1 Adds helper to check HDMI2.1 DSC1.2 Patch 2 resets 'frl trained' flag before restarting FRL training. Patch 3 Pulls the decision making to use DFP conversion capabilities for every mode during compute config, instead of having that decision during DP initializing phase. Patch 4-5 calculate the max BPC that can be sufficient with either RGB or YCbcr420 format for the maximum FRL rate supported.
