Please let me know if my suggested description would be fine. Either I miss some more pieces or this is wrong design. The phy node should not be used to pass some addresses somewhere. It is used to define a device which will be instantiated (as parent is simple-mfd). If you use it only to obtain some address, not to describe child device, then this is wrong property type.
