+* Armada 37xx CPU Watchdog Timer Controller
+
+Required properties:
+- compatible : must be "marvell,armada-3700-wdt"
+- reg : base physical address of the controller and length of memory mapped
+ region.
+- clocks : the clock feeding the watchdog timer. See clock-bindings.txt
+- marvell,system-controller : reference to syscon node for the CPU Miscellaneous
+ Registers
+
+Example:
+
+ cpu_misc: system-controller@d000 {
+ compatible = "syscon", "simple-mfd";
+ reg = <0xd000 0x1000>;
+ };
+
+ wdt: watchdog-timer@8300 {
+ compatible = "marvell,armada-3700-wdt";
+ reg = <0x8300 0x40>;
+ marvell,system-controller = <&cpu_misc>;
+ clocks = <&xtalclk>;
+ };
