+Required properties:
+- compatible: "men,a021-wdt"
+- gpios: Specifies the pins that control the Watchdog, order:
+ 1: Watchdog enable
+ 2: Watchdog fast-mode
+ 3: Watchdog trigger
+ 4: Watchdog reset cause bit 0
+ 5: Watchdog reset cause bit 1
+ 6: Watchdog reset cause bit 2

+Example:
+ watchdog {
