[Intel-gfx] [v7 01/16] drm: Add Enhanced Gamma LUT precision structure

2019-03-28 Thread Uma Shankar
Existing LUT precision structure is having only 16 bit precision. This is not enough for upcoming enhanced hardwares and advance usecases like HDR processing. Hence added a new structure with 32 bit precision values. Also added the code, for extracting the same from values passed from userspace.
