From: Ville Syrjälä <[email protected]> Just like we did for pipe gamma, let's also track the pipe csc state. The hardware only exists on ILK+, and currently we always enable it on hsw+ and never on any other platforms. Just like with pipe gamma, the primary plane control register is used for the readout on pre-SKL, and the pipe bottom color register on SKL+.
