14   strength increases based on the duty cycle of the enable PWM channel
15   (100% duty cycle meaning strongest vibration, 0% meaning no vibration).
17   The binding supports an optional direction PWM channel, that can be
18   driven at fixed duty cycle. If available this is can be used to increase
