-* PWM vibrator device tree bindings
-
-Registers a PWM device as vibrator. It is expected, that the vibrator's
-strength increases based on the duty cycle of the enable PWM channel
-(100% duty cycle meaning strongest vibration, 0% meaning no vibration).
-
-The binding supports an optional direction PWM channel, that can be
-driven at fixed duty cycle. If available this is can be used to increase
-the vibration effect of some devices.
-
-Required properties:
-- compatible: should contain "pwm-vibrator"
-- pwm-names: Should contain "enable" and optionally "direction"
-- pwms: Should contain a PWM handle for each entry in pwm-names
-
-Optional properties:
-- vcc-supply: Phandle for the regulator supplying power
-- direction-duty-cycle-ns: Duty cycle of the direction PWM channel in
- nanoseconds, defaults to 50% of the channel's
- period.

-
