Implement CTM color management property for OMAP CRTC using DSS overlay manager's Color Phase Rotation matrix. The CPR matrix does not exactly match the CTM property documentation. On DSS the CPR matrix is applied after gamma table look up. However, it seems stupid to add a custom property just for that.

Should this be updated now that the driver has switched to using degamma ?

Right, good catch. I think I can just drop everything after the first sentence.
