So especially in the case where there is a dedicated socket for it, as you write, we should definitly add it for the board. By the way, am I correct in thinking that patch 1 and 2 are actually independent of each other? So I'd just pick patch2 for the Rockchip tree (as we do have a text-binding) and you can handle the yaml conversion in a followup or whatever? Thanks Heiko
