It also includes other minor HDMI2.1 PCON fixes/refactoring. Patch 1-2 Have minor fixes/cleanups. Patch 3-6 Pull the decision making to use DFP conversion capabilities for every mode during compute config, instead of having that decision during DP initializing phase. Patch 7-8 Calculate the max BPC that can be sufficient with either RGB or YCbcr420 format for the maximum FRL rate supported. Rev2: Split the refactoring of DFP RG->YCBCR conversion into smaller patches, as suggested by Jani N. Also dropped the unnecessary helper for DSC1.2 support for HDMI2.1 DFP. Rev3: As suggested by Ville, added new member sink_format to store the final format that the sink will be using, which might be different than the output format, and thus might need color/format conversion performed by the PCON.
