+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>;
+ regulator-enable-ramp-delay = <256>;
+ regulator-allowed-modes = <0 1 2 4>;
+ };
+
+ mt6315_3_vbuck3: vbuck3 {
