Sure, this is fine. Why don't you simply do like this? reg_3p3v: regulator-3p3v { compatible = "regulator-fixed"; regulator-name = "3P3V"; regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; }; -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
