When parsing the DT, you can convert from phandle (or struct device_node *) to the name of the referenced supply by simple lookup. So, you could store supply names rather than device_node *. Can't you then also fill in the referenced supply's existing char** list of supplies? Of course, making this interact-with/use -EPROBE_DEFERRED might be challenging, since this would be operating in the inverse order to other producer/consumer relationships, which might cause loops. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
