2015-11-09 Thread Patrik Jakobsson
Handle DC off as a power well where enabling the power well will prevent the DMC to enter selected DC states (required around modesets and Aux A). Disabling the power well will allow DC states again. For now the highest DC state is DC6 for Skylake and DC5 for Broxton but will be configurable for
