Do we have a use case for a different implementation other than the simplest case? If not, it seems to me this will just become redundant boilerplate code (every platform will use the simple xlate method). > This function again is to support the phandle + args specifier way of > requesting hwlocks, the hwspin_lock_request_specific() is invoked > internally within this function, so we are still reusing the actual > request code other than handling the DT parsing portion.

I think you may have misunderstood me, sorry. I'm ok with the phandle + args specifier. I just think we can use it, together with the base_id property, to infer the global lock id from the DT data. This is not only a must to support heterogenous multi-processing systems, it will also substantially simplify the code.
