+MediaTek MT6380 Regulator
+
+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:

+STM32 VREFBUF - Voltage reference buffer

+- compatible:		Must be "st,stm32-vrefbuf".
+- reg:			Offset and length of VREFBUF register set.
