But it doesn't say anything about the ranges property. Isn't the dtc warning in fact over-zealous? The ePAPR says that the unit address should be the first address of the reg property, but doesn't say anything about the ranges property. What I dislike is that there absolutely nothing that forces the ranges to be written in this order. In another board, it can be written in a completely different order, which means that the unit address would be different, which is really silly. I continue to believe this rule doesn't make sense, and the soc node shouldn't have a unit address. Maybe Rob or Mark (who is not in Cc, for some reason?) should say a word about this?
