[PATCH v5 00/17] New uAPI drm properties for color management

[Werner Sembach]

Implementation of https://lkml.org/lkml/2021/5/12/764 now feature complete
albeit not fully tested.

I have now corrected the DSC behavior, but still no wait to test it.

Exact dithering behavior remains a mistery so in case dithering is active it's
not 100% clear what "active bpc" means, or where the "max bpc" limit is applied.

I have no DP MST splitter at hand. I tried my best to not break anything,
but if one who has one could test it would be very helpful.

Things on my TODO list:
    - add "min bpc" property
    - rewrite "preferred color format" to "force color format"
    - make "Broadcast RGB" only affect RGB on AMD too
    - remove unreachable enums of "active/preferred/force color format"
