echo-gpios:
description:
Definition of the GPIO for the echo (input)
This GPIO is set by the device as soon as an ultrasonic burst is sent
out and reset when the first echo is received.
Thus this GPIO is set while the ultrasonic waves are doing one round
trip.
It needs to be an GPIO which is able to deliver an interrupt because
the time between two interrupts is measured in the driver.

description:
Definition of the GPIO for power management of connected peripheral

it's switched on again. After some period of inactivity the driver
get suspended automatically (autosuspend feature).
