+* 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@...c3450 {
+	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>;
+};
