Doing this with a runtime call just feels badly joined up, and there's nothing here which hands off the configuration between the various drivers involved in the transitions. We need to make sure that the voltage doesn't suddenly lurch around when doing transitions. There's also a lack of locking in the code which would seem to be required and I'd expect regulator_set_external_ctl() to return an error if it fails. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
