+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 a=
t
+  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 us=
b33
+
+Example:
+
+pwr_regulators: pwr@50001000 {
+	compatible =3D "st,stm32mp1,pwr-reg";
+	reg =3D <0x50001000 0x10>;
+	vdd-supply =3D <&vdd>;
+	vdd_3v3_usbfs-supply =3D <&vdd_usb>;
+
+	reg11: reg11 {
+		regulator-name =3D "reg11";
+		regulator-min-microvolt =3D <1100000>;
+		regulator-max-microvolt =3D <1100000>;
+	};
+
+	reg18: reg18 {
+		regulator-name =3D "reg18";
+		regulator-min-microvolt =3D <1800000>;
+		regulator-max-microvolt =3D <1800000>;
+	};
+
+	usb33: usb33 {
+		regulator-name =3D "usb33";
+		regulator-min-microvolt =3D <3300000>;
+		regulator-max-microvolt =3D <3300000>;
+	};
