| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some code may want to read reg values from DT, but from nodes that aren't associated with DM devices, so using dev_get_addr_index() isn't appropriate. In this case, fdtdec_get_addr_size_*() are the functions to use. However, "translation" (via the chain of ranges properties in parent nodes) may still be desirable.
