1STM32 VREFBUF - Voltage reference buffer
2
3Some STM32 devices embed a voltage reference buffer which can be used as
4voltage reference for ADCs, DACs and also as voltage reference for external
5components through the dedicated VREF+ pin.

7Required properties:
8- compatible:		Must be "st,stm32-vrefbuf".
9- reg:			Offset and length of VREFBUF register set.
10- clocks:		Must contain an entry for peripheral clock.
11
12Optional properties:
13- vdda-supply:		Phandle to the parent vdda supply regulator node.

15Example:
16	vrefbuf: regulator@58003c00 {
17		compatible = "st,stm32-vrefbuf";
18		reg = <0x58003C00 0x8>;
19		clocks = <&rcc VREF_CK>;
20		regulator-min-microvolt = <1500000>;
21		regulator-max-microvolt = <2500000>;
22		vdda-supply = <&vdda>;
23	};
