Since I would like to move forward so I can one day use that binding in a real-life product, I am going to go for Mark's side which happens to be how I want the binding to look like. Do we all agree that the new binding is just way better than the old one? In light of the recent unstable DT ABI discussion, we can still continue parsing the old one for the sake of compatibility. -- Florian -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
