* 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>;
};
