Move VRR enabling/disabling into a place where it also works for fastsets. With this we always start the transcoder up in non-VRR mode. Granted we already did that but for a very short period of time. But now that we might end up doing a bit more with the transcoder in non-VRR mode it seems prudent to also update the active timings as the transcoder changes its operating mode. crtc_state->vrr.enable still tracks whether VRR is actually enabled or not, but now we configure all the other VRR timing registers whenever VRR is possible (whether we actually enable it or not). crtc_state->vrr.flipline can now serve as our "is VRR possible" bit of state. I decided to leave the MSA timing ignore bit set all the time whether VRR is actually enabled or not. If the sink can figure out the timings with that information when VRR is active then surely it can also do it when VRR is inactive. v2: Protect intel_vrr_set_transcoder_timings() with HAS_VRR() Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230321135615.27338-1-ville.syrjala@linux.intel.com Reviewed-by: Mitul Golani <mitulkumar.ajitkumar.golani@intel.com>
