Dynamic Refresh Rate Switching (DRRS) is a power conservation feature which enables swtiching between low and high refresh rates based on the usage scenario. This feature is applciable for internal eDP panel. Indication that the panel supports DRRS is given by the panel EDID, which would list multiple refresh rates for one resolution. The patch series supports idleness detection in display i915 driver and switch to low refresh rate. Based on review comments, the functions for idleness detection have been restructured. DRRS idleness time has been modified to be a kernel module param. Added support for VLV.
