I wonder if we should leave support for old device trees files around, at least for a while. Your patch removes a lot of unnecessary code if we decide not to worry about backwards compatibility here, but I could imagine that we see a few surprises here. > +- dma-names: Must be "ssp". I would prefer calling this "data" rather than "ssp". The name only has local significance in the ssp device, so calling the channel "ssp" seems wrong.
