+AXP20x USB power supply
+
+Required Properties:
+-compatible: One of: "x-powers,axp202-usb-power-supply"
+ "x-powers,axp221-usb-power-supply"
+ "x-powers,axp223-usb-power-supply"
+ "x-powers,axp813-usb-power-supply"
+
+The AXP223 PMIC shares most of its behaviour with the AXP221 but has slight
+variations such as the former being able to set the VBUS power supply max
+current to 100mA, unlike the latter.
+
+This node is a subnode of the axp20x PMIC.
+
+Example:
+
+axp209: pmic@34 {
+ compatible = "x-powers,axp209";
+ reg = <0x34>;
+ interrupt-parent = <&nmi_intc>;
+ interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-controller;
+ #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";
+ };
+
+ ...
+ };
+
+ usb-power-supply: usb-power-supply {
+ compatible = "x-powers,axp202-usb-power-supply";
+ };
+};
