-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>;
-	};
