I would expect that the device tree bindings for these features would be added as the features are added and the DTS files updated, for example by listing additional compatible strings if that was the binding update, as is the normal practice. Obviously any hardware which is not compatible with the current binding should not be being registered using the current binding. It is not clear from the above comment by Sebastian if he is referring to the same set of hardware differences or something new - doing things based on device address is highly unusual, it sounds like something to do with the integration into the SoC rather than to do with the IP.
