This generally looks good to me. I'm inclined to merge the kernel
parts now and sort the spec addition out afterwards. With no users
yet, we can still tweak things if needed.

I would like to see more comments on this though. Perhaps "OF phandle
nexus" is too obscure. Maybe "Add DT overlay connector bindings" would
trick some people in looking at it...
