+MediaTek MT6380 Regulator Driver
+
+All voltage regulators are defined as subnodes of the regulators node. A list
+of regulators provided by this controller are defined as subnodes of the
+PMIC's 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
+
+Example:
+
+       regulators {
+               compatible = "mediatek,mt6380-regulator";
