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.
