Not sure if reusing reg for this is the correct way or if another property such as "multi_index" or similar should be used instead. Looks like reg is used for similar things at least. Or should the whole "reverse the devicetree" problem be fixed instead? Update bindings to match implementation, and add description for the reg property.
