+Required properties:
+- compatible: "mediatek,mt6311-regulator"
+- reg: I2C slave address, usually 0x6b.
+- regulators: List of regulators provided by this controller. It is named
+  to VDVFS and VBIASN.
+  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:
+  VDVFS
+LDO:
+  VBIASN
+
+Example:
+	mt6311: pmic@6b {
+		compatible = "mediatek,mt6311-regulator";
+		reg = <0x6b>;
+
+		regulators {
+			mt6311_vcpu_reg: VDVFS {
+				regulator-name = "VDVFS";
+				regulator-min-microvolt = < 600000>;
+				regulator-max-microvolt = <1400000>;
+				regulator-ramp-delay = <10000>;
+			};
+			mt6311_ldo_reg: VBIASN {
+				regulator-name = "VBIASN";
+				regulator-min-microvolt = <200000>;
+				regulator-max-microvolt = <800000>;
+			};
+		};
