This started to conflict with commit dd286a531461748f ("v4l: vsp1:
Start and stop DRM pipeline independently of planes"), causing build
failures as it changes the signature of vsp1_entity_route_setup(), and
removed several VSP1_ENTITY_PARAMS_* definitions.
After fixing those, it hangs after:
[drm] No driver support for vblank timestamp query.
So I dropped the above for today's release.
