Indeed.

As the dependencies are now in linux-next, I'm queueing this in
renesas-devel for v5.11, after fixing all conflicts due to recent
additions, and sorting &lvds0 before &pfc.

This also needs changing vcc-supply to power-supply for lvds receiver due to recent binding changes, probably Ill do the above and post a v3.

Oh, I didn't know that.  So please send a v3, so I can replace the commit
