Dynamic Refresh Rate Switching (DRRS) is a power conservation feature which
enabled 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.
