[RFC V1 0/6] Add Plane Color Properties

[Uma Shankar <uma.shankar@intel.com>]

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. 

Uma Shankar (6):

  drm: Add Plane CTM property
  drm: Add Plane Gamma properties
  drm: Define helper function for plane color enabling
  drm: Define helper to set legacy gamma table size
  drm/i915: Enable plane color features
