+Required properties:
+- compatible		: Should be "xlnx,zynq-wdt-r1p2" or "cdns,wdt-r1p2".
+- clocks		: Clock phandles (see clock bindings for details).
+- reg			: Physical base address and size of WDT registers map.
+- interrupts		: Property with a value describing the interrupt
+			  number.
+- interrupt-parent	: Must be core interrupt controller.
+
+Optional properties
+- reset			: Reset interrupt.
+- timeout-sec		: Watchdog timeout value (in seconds).
+
+Example:
+
+		wdt@f8005000 {
+			compatible = "xlnx,zynq-wdt-r1p2";
+			clocks = <&clkc 45>;
+			interrupt-parent = <&intc>;
+			interrupts = <0 9 1>;
+			reg = <0xf8005000 0x1000>;
+			reset = <0>;
+			timeout-sec = <10>;
+		} ;
