-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@...03c00 {
-		compatible = "st,stm32-vrefbuf";
-		reg = <0x58003C00 0x8>;
-		clocks = <&rcc VREF_CK>;
-		regulator-min-microvolt = <1500000>;
-		regulator-max-microvolt = <2500000>;
-		vdda-supply = <&vdda>;
-	};
