| 2 | |
| 3 | Required properties: |
| 4 | - compatible : should be "gpio-poweroff". |
| 5 | - gpios : The GPIO to set high/low, see "gpios property" in |
| 6 | Documentation/devicetree/bindings/gpio/gpio.txt. If the pin should be |
| 7 | low to power down the board set it to "Active Low", otherwise set |
| 8 | gpio to "Active High". |
| 9 | |
| 10 | Optional properties: |
| 11 | - input : Initially configure the GPIO line as an input. Only reconfigure |
| 12 | it to an output when the pm_power_off function is called. If this optional |
| 13 | property is not specified, the GPIO is initialized as an output in its |
| 14 | inactive state. |

| 17 | Examples: |
| 18 | |
| 19 | gpio-poweroff { |
| 20 | compatible = "gpio-poweroff"; |
| 21 | gpios = <&gpio 4 0>; /* GPIO 4 Active Low */ |
| 22 | }; |
