+* Device tree bindings for the Qualcomm MSM vibrator
+
+Required properties:
+
+ - compatible: Should be one of
+ "qcom,msm8226-vibrator"
+ "qcom,msm8974-vibrator"
+ - reg: the base address and length of the IO memory for the registers.
+ - pinctrl-names: set to default.
+ - pinctrl-0: phandles pointing to pin configuration nodes. See
+ Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
+ - clock-names: set to pwm
+ - clocks: phandle of the clock. See
+ Documentation/devicetree/bindings/clock/clock-bindings.txt
+ - enable-gpios: GPIO that enables the vibrator.
+
+Optional properties:
+
+ - vcc-supply: phandle to the regulator that provides power to the sensor.
+
+Example from a LG Nexus 5 (hammerhead) phone:
+
+vibrator@fd8c3450 {
+ reg = <0xfd8c3450 0x400>;
+ compatible = "qcom,msm8974-vibrator";
+
+ vcc-supply = <&pm8941_l19>;
+
+ clocks = <&mmcc CAMSS_GP1_CLK>;
+ clock-names = "pwm";
+
+ enable-gpios = <&msmgpio 60 GPIO_ACTIVE_HIGH>;
+
+ pinctrl-names = "default";
+ pinctrl-0 = <&vibrator_pin>;
+};
