Do I take that to mean that we'll merge it through the subsystem tree,
and not go through some common DT tree?
Thanks,

Yes, that's generally the case when bindings are in a series with driver changes. Rob

Alright, thanks. I've applied patches 1-3, patch 4 obviously still needs work (and probably won't go through my tree anyway.) Note that I made some documentation fixes in patch 3, Rafał, please check. johannes

Looks great, thanks everyone for your help on getting this patchset in shape!
