   2
   3 Required properties:
   4
   5   - compatible: Should be one of
   6                 "qcom,msm8226-vibrator"
   7                 "qcom,msm8974-vibrator"
   8   - reg: the base address and length of the IO memory for the registers.
   9   - pinctrl-names: set to default.
  10   - pinctrl-0: phandles pointing to pin configuration nodes. See
  11                Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
  12   - clock-names: set to pwm
  13   - clocks: phandle of the clock. See
  14             Documentation/devicetree/bindings/clock/clock-bindings.txt
  15   - enable-gpios: GPIO that enables the vibrator.
  16
  17 Optional properties:
  18
  19   - vcc-supply: phandle to the regulator that provides power to the sensor.

  25         compatible = "qcom,msm8974-vibrator";
  26
  27         vcc-supply = <&pm8941_l19>;
  28
  29         clocks = <&mmcc CAMSS_GP1_CLK>;
  30         clock-names = "pwm";
  31
  32         enable-gpios = <&msmgpio 60 GPIO_ACTIVE_HIGH>;
  33
  34         pinctrl-names = "default";
  35         pinctrl-0 = <&vibrator_pin>;
  36 };
