Hi Quentin

I assume breaking backwards compatibility is not an issue here, since
there currently is only one board using the DT binding. But it would
be good to give a warning in the cover notes. git bisect will also
break for this one particular board. And since these changes are going
through different trees, it could be quite a big break.
