It allows abstraction of hardware color correction and enhancement capabilities by virtue of DRM properties. There are two major types of color correction supported by DRM color manager: - CTM: color transformation matrix, properties where a correction matrix is used for color correction. - Palette correction: Where direct LUT values are sent to be applied on a color palette. This patch initializes color management framework by: 1. Introducing new pointers in DRM mode_config structure to carry CTM and Palette color correction properties. 2. Creating these DRM properties in DRM standard properties creation sequence.
