-* 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 {
