-Required properties:
-- compatible : should be "gpio-poweroff".
-- gpios : The GPIO to set high/low, see "gpios property" in
- Documentation/devicetree/bindings/gpio/gpio.txt. If the pin should be
- low to power down the board set it to "Active Low", otherwise set
- gpio to "Active High".
-
-Optional properties:
-- input : Initially configure the GPIO line as an input. Only reconfigure
- it to an output when the power-off handler is called. If this optional
- property is not specified, the GPIO is initialized as an output in its
- inactive state.
-- active-delay-ms: Delay (default 100) to wait after driving gpio active
-- inactive-delay-ms: Delay (default 100) to wait after driving gpio inactive
-- timeout-ms: Time to wait before asserting a WARN_ON(1). If nothing is
- specified, 3000 ms is used.

-Examples:
-
-gpio-poweroff {

- gpios = <&gpio 4 0>;
- timeout-ms = <3000>;
