Good question. >From datasheet GPO's are marked as LV (Low Voltage)-> 3.1V Power Gates Driver are marked as EMV (Extended Medium Voltage) -> 5.5V and no way to modify that -> they are fixed regulators. I will add voltage query capability. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
