-Subject: [PATCH] drm/vc4: Add more display planes to each CRTC.
-
-Previously we only did the primary and cursor plane, but overlay
-planes are useful and just require this setup to add, since all planes
-go into the HVS display list in the same way.

-(cherry picked from commit fc2d6f1eabee9d971453da2a27a72471c2a347dd)
