1* Armada 37xx CPU Watchdog Timer Controller
2
3Required properties:
4- compatible : must be "marvell,armada-3700-wdt"
5- reg : base physical address of the controller and length of memory mapped
6	region.
7- clocks : the clock feeding the watchdog timer. See clock-bindings.txt
8- marvell,system-controller : reference to syscon node for the CPU Miscellaneous
9	Registers

11Example:
12
13	cpu_misc: system-controller@d000 {
14		compatible = "marvell,armada-3700-cpu-misc", "syscon";
15		reg = <0xd000 0x1000>;
16	};
17
18	wdt: watchdog@8300 {
19		compatible = "marvell,armada-3700-wdt";
20		reg = <0x8300 0x40>;
21		marvell,system-controller = <&cpu_misc>;
22		clocks = <&xtalclk>;
23	};
