From: Ville Syrjälä <[email protected]> The limited color range knob is in the port registers on g4x and vlv/chv for HDMI, and on g4x for DP. Add the relevant code to read out the hardware state into pipe config. On vlv/chv the DP port limited color range knob is in PIPECONF for which we already have readout code.
