* 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 = "marvell,armada-3700-cpu-misc", "syscon";

		reg = <0xd000 0x1000>;

	};



	wdt: watchdog@8300 {

		compatible = "marvell,armada-3700-wdt";

		reg = <0x8300 0x40>;

		marvell,system-controller = <&cpu_misc>;

		clocks = <&xtalclk>;

	};
