+STM32MP1 PWR Regulators
+-----------------------
+
+Available Regulators in STM32MP1 PWR block are:
+ - reg11 for regulator 1V1
+ - reg18 for regulator 1V8
+ - usb33 for the swtich USB3V3
+
+Required properties:
+- compatible: Must be "st,stm32mp1,pwr-reg"
+- list of child nodes that specify the regulator reg11, reg18 or usb33
+ initialization data for defined regulators. The definition for each of
+ these nodes is defined using the standard binding for regulators found at
+ Documentation/devicetree/bindings/regulator/regulator.txt.
+- vdd-supply: phandle to the parent supply/regulator node for vdd input
+- vdd_3v3_usbfs-supply: phandle to the parent supply/regulator node for usb33
+
+Example:
+
+pwr_regulators: pwr@50001000 {
+ compatible = "st,stm32mp1,pwr-reg";
+ reg = <0x50001000 0x10>;
+ vdd-supply = <&vdd>;
+ vdd_3v3_usbfs-supply = <&vdd_usb>;
+
+ reg11: reg11 {
+ regulator-name = "reg11";
+ regulator-min-microvolt = <1100000>;
+ regulator-max-microvolt = <1100000>;
+ };
+
+ reg18: reg18 {
+ regulator-name = "reg18";
+ regulator-min-microvolt = <1800000>;
+ regulator-max-microvolt = <1800000>;
+ };
+
+ usb33: usb33 {
+ regulator-name = "usb33";
+ regulator-min-microvolt = <3300000>;
+ regulator-max-microvolt = <3300000>;
+ };
+};
