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.

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.
