This patch series adds properties for plane color features. It adds properties for degamma used to linearize data, CSC used for gamut conversion, and gamma used to again non-linearize data as per panel supported color space. These can be utilize by user space to convert planes from one format to another, one color space to another etc. Usersapce can take smart blending decisions and utilize these hardware supported plane color features to get accurate color profile. The same can help in consistent color quality from source to panel taking advantage of advanced color features in hardware. These patches just add the property interfaces and enable helper functions. Based on community feedabck on this one, we can build up and add hardware specific implementation on top of this series. Note: This is just to get a design feedback whether these interfaces look ok. Once, designed is agreed will re-send the series with a hardware specific implementation along with IGT tests for plane color.
