-* 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>;
-	};
