Unless there's a compelling reason to drop a binding, and all users are happy with it being dropped, then there's not much point in removing it. It's usually not possible to get agreement because it's usually nto possible to know the full set of users, so in general we can't drop or change stuff. > Though, you still want to move the DTs to use common mmc bindings.

As far as I can see, keeping the existing binding along side the new one looks relatively simple in this case.
