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>;

	};
