+Mediatek MT6315 Regulator
+
+Required properties:
+- compatible: Must be one of the following.
+	"mediatek,mt6315_3-regulator"
+	"mediatek,mt6315_6-regulator"
+	"mediatek,mt6315_7-regulator"
+- reg: SPMI slave id.
+- regulators: List of regulators provided by this controller.
+  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:
+  vbuck1, vbuck3, vbuck4
+
+Example:
+	mt6315_3: mt6315@3 {
+		compatible = "mediatek,mt6315_3-regulator";
+		reg = <0x3 0 0xb 1>;
+
+		mt6315_3_vbuck1: vbuck1 {
+			regulator-compatible = "vbuck1";
+			regulator-min-microvolt = <300000>;
+			regulator-max-microvolt = <1193750>;
+			regulator-enable-ramp-delay = <256>;
+			regulator-allowed-modes = <0 1 2 4>;
+		};
+
+		mt6315_3_vbuck3: vbuck3 {
+			regulator-compatible = "vbuck3";
+			regulator-min-microvolt = <300000>;
+			regulator-max-microvolt = <1193750>;
