We also set up the sdmmc host without knowing if the user will plug in
an sd-card ;-) .

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
