| 2 | |
| 3 | Describes a simple watchdog timer which is reset by toggling a gpio. |
| 4 | |
| 5 | Required properties: |
| 6 | |
| 7 | - compatible: Must be "linux,wdt-gpio". |
| 8 | - gpios: gpio to toggle when wdt driver reset method is called. |
| 9 | - always-running: Boolean property indicating that the watchdog cannot |
| 10 | be disabled. At present, U-Boot only supports this kind of GPIO |
| 11 | watchdog. |
| 12 | |
| 13 | Example: |
| 14 | |
| 15 | gpio-wdt { |
| 16 | gpios = <&gpio0 1 0>; |
| 17 | compatible = "linux,wdt-gpio"; |
| 18 | always-running; |
| 19 | }; |
