intel_dp_set_drrs_state — program registers for RR switch to take effect
void intel_dp_set_drrs_state ( | struct drm_device * dev, |
int refresh_rate); |
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.
