Dynamic Refresh Rate Switching (DRRS) is a power conservation feature which     
enables switching between low and high refresh rates based on the usage         
scenario. This feature is applicable for internal eDP panel. Indication that    
the panel can support 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.
