From DT point of view, in general, drivers should be asking for a
specific port number because their function is fixed in the binding.

of_graph_get_next_endpoint() doesn't match to this concept.

Simply replace

        - of_graph_get_next_endpoint(xxx, NULL);
        + of_graph_get_endpoint_by_regs(xxx, 0, -1);
