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>;

	};

};
