+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>;
+ };
