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. Andrew
