  This module is part of the ROHM BD71828 MFD device. For more details

  see Documentation/devicetree/bindings/mfd/rohm,bd71828-pmic.yaml.

  The regulator controller is represented as a sub-node of the PMIC node

  on the device tree.

  Regulator nodes should be named to BUCK_<number> and LDO_<number>.

  The valid names for BD71828 regulator nodes are

  BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6, BUCK7

  LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7

STM32 BOOSTER - Booster for ADC analog input switches

Some STM32 devices embed a 3.3V booster supplied by Vdda, that can be used

to supply ADC analog input switches.

Required properties:

- compatible: Should be one of:

  "st,stm32h7-booster"

  "st,stm32mp1-booster"

- st,syscfg: Phandle to system configuration controller.

- vdda-supply: Phandle to the vdda input analog voltage.

Example:

	booster: regulator-booster {

		compatible = "st,stm32mp1-booster";

		st,syscfg = <&syscfg>;

		vdda-supply = <&vdda>;

	};

STM32 VREFBUF - Voltage reference buffer

Some STM32 devices embed a voltage reference buffer which can be used as

voltage reference for ADCs, DACs and also as voltage reference for external

components through the dedicated VREF+ pin.

Required properties:

- compatible:		Must be "st,stm32-vrefbuf".

- reg:			Offset and length of VREFBUF register set.

- clocks:		Must contain an entry for peripheral clock.

Example:

	vrefbuf: regulator@58003c00 {

		compatible = "st,stm32-vrefbuf";

		reg = <0x58003C00 0x8>;

		clocks = <&rcc VREF_CK>;

		regulator-min-microvolt = <1500000>;

		regulator-max-microvolt = <2500000>;

		vdda-supply = <&vdda>;
