+Zynq Watchdog Device Tree Bindings
+-------------------------------------------
+
+Required properties:
+- compatible            : Should be "cdns,wdt-r1p2".
+- clocks                : This is pclk (APB clock).
+- interrupts            : This is wd_irq - watchdog timeout interrupt.
+- interrupt-parent      : Must be core interrupt controller.
+
+Optional properties
+- reset-on-timeout      : If this property exists, then a reset is done
+                          when watchdog times out.
+- timeout-sec           : Watchdog timeout value (in seconds).
+
+Example:
+        watchdog@f8005000 {
+                compatible = "cdns,wdt-r1p2";
+                clocks = <&clkc 45>;
+                interrupt-parent = <&intc>;
+                interrupts = <0 9 1>;
+                reg = <0xf8005000 0x1000>;
+                reset-on-timeout;
+                timeout-sec = <10>;
+        };
