+Bindings for MEN A21 Watchdog device connected to GPIO lines
+
+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
+
+Optional properties:
+- None
+
+Example:
+ watchdog {
+ compatible ="men,a021-wdt";
+ gpios = <&gpio3 9 1 /* WD_EN */
+ &gpio3 10 1 /* WD_FAST */
+ &gpio3 11 1 /* WD_TRIG */
+ &gpio3 6 1 /* RST_CAUSE[0] */
