From: Ville Syrjälä <[email protected]> In order to move VRR enable/disable to a place where it's also applicable to fastsets we need to be prepared to configure the pipe into non-VRR mode initially, and then later switch to VRR mode. To that end allow the active timings to be configured in non-VRR mode temporarily even when the crtc_state says we're going to be using VRR.
