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;
|
||
|
|
};
