I still don't think this change is necessary. Just because a hardware block in DT maps to different subsystems in a particular OS doesn't mean you need a DT node for each OS subsystem. What we have subsystems for changes over time and DT shouldn't really be changing based on that. And DT is not the only way to instantiate drivers. Rob
