+* Regulator vibrator device tree bindings
+
+Required Properties:
+ - compatible : Should be "regulator-vibrator"
+ - vibr-supply : Power supply to the vibrator.
+	[*] refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+ - max-volt : The maximum voltage value supplied to the vibrator regulator.
+		[The unit of the voltage is a micro]
+
+ - min-volt : The minimum voltage value supplied to the vibrator regulator.
+		[The unit of the voltage is a micro]
+
+Optional properties:
+ - min-limit : Set the minimum time in ms for vibrator , default is 15ms,
+		if user request duration is smaller, this value will be used instead.
+		the default value comes from the smallest unit that can be sensed.
+
+ - max-limit : Set the maximum time in ms for vibrator.
+		if not set, it means no max limitation.
+
+Example:
+
+	mt6359_vibr_ldo_reg: ldo_vibr {
+		regulator-name = "vibr";
+		regulator-min-microvolt = <1200000>;
+		regulator-max-microvolt = <3300000>;
+		regulator-enable-ramp-delay = <240>;
+	};
+
+	regulator_vibrator {
+		compatible = "regulator-vibrator";
+		min-volt = <2300000>;
+		max-volt = <3200000>;
+		max-limit = <15000>;
+		min-limit = <15>;
+		vib-supply = <&mt6359_vibr_ldo_reg>;
+	};
