+Required Properties:
+-compatible: "x-powers,axp202-usb-power-supply"

+This node is a subnode of the axp20x PMIC.

+	reg = <0x34>;
+	interrupt-parent = <&nmi_intc>;

+	#interrupt-cells = <1>;
+
+	regulators {
+		x-powers,dcdc-freq = <1500>;
+
+		vdd_cpu: dcdc2 {
+			regulator-always-on;
+			regulator-min-microvolt = <1000000>;
+			regulator-max-microvolt = <1450000>;
+			regulator-name = "vdd-cpu";
