intel_dp_set_drrs_state — program registers for RR switch to take effect
|struct drm_device * dev,|
This function gets called when refresh rate (RR) has to be changed from one frequency to another. Switches can be between high and low RR supported by the panel or to any other RR based on media playback (in this case, RR value needs to be passed from user space).
The caller of this function needs to take a lock on dev_priv->drrs.
