From: Shashank Sharma <shashank.sharma@xxxxxxxxx>
In valleyview we have three possible sprite plane level
color correction:
1. Contrast
2. Brightness
What this patch does:
1. This patch adds software infrastructure to register plane level
color correction properties per plane. Adding a new function,
intel_attach_plane_color_correction to register the plane level
color correction properties.
2. Adding a pointer in intel_plane structure to store this property.
3. Adding structure gen6_plane_color_corrections, which contains different
plane level correction values for VLV.
