Do we have a use case today that require the xlate() method? If not, let's remove it as we could always add it back if some new hardware shows up that needs it. As long as the dt data is unchanged, we should generally only add kernel code that we really need. > 3.

It seems to me we can just introduce a of_hwspin_lock_get_id() method which will provide the global lock id to dt users, with which they could just invoke the existing hwspin_lock_request_specific(). This way we will have more common code between dt users and users who get the lock id from a remote processor.
