-Subject: [PATCH] drm/vc4: Add support for setting DPMS in firmwarekms.
-
-This ensures that the screen goes blank during DPMS (screensaver),
-including the cursor. Planes don't necessarily get disabled during
-CRTC disable, so we need to be careful to not leave them on or turn
-them back on early.
