    On the Jetson TX2 patches for LP0 support we added a couple of other
    properties that we don't have in the Jetson TX1 device tree yet. For
    example:

    linux,input-type = <EV_KEY>;

    which is probably harmless, but we may want to add it on Jetson TX1
    eventually anyway.

    debounce-interval = <10>;

    May be good an Jetson TX1 as well.

    wakeup-event-action = <EV_ACT_ASSERTED>;

    I vaguely recall this to be necessary for some reason, but I may be
    wrong.
