I'm still not seeing how this would cause an issue. The only Device Tree 
nodes which will be parsed are the ones which are specified by a 
particular driver's compatible string, meaning that any other nodes 
referencing similar regulator/supply names would be ignored. In case I 
am still missing a critical point here, would you be kind enough to 
provide an example that we can work though together?
