| GPIO watchdog timer | |
| Describes a simple watchdog timer which is reset by toggling a gpio. | |
| Required properties: | |
| - compatible: Must be "linux,wdt-gpio". | |
| - gpios: gpio to toggle when wdt driver reset method is called. | |
| - always-running: Boolean property indicating that the watchdog cannot | |
| be disabled. At present, U-Boot only supports this kind of GPIO | |
| watchdog. | |
| Example: | |
| gpio-wdt { | |
| gpios = <&gpio0 1 0>; | |
| compatible = "linux,wdt-gpio"; | |
| always-running; | |
| }; |
