+All voltage regulators provided by the MT6380 PMIC are described as the
+subnodes of the MT6380 regulators node. Each regulator is named according
+to its regulator type, buck-<name> and ldo-<name>. The definition for each
+of these nodes is defined using the standard binding for regulators at
+Documentation/devicetree/bindings/regulator/regulator.txt.
+
+The valid names for regulators are:
+BUCK:
+  buck-core1, buck-vcore, buck-vrf
+LDO:
+  ldo-vm ,ldo-va , ldo-vphy, ldo-vddr, ldo-vt

+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>;
