-Required properties:
-- compatible : Should be "cdns,wdt-r1p2".
-- clocks : This is pclk (APB clock).
-- interrupts : This is wd_irq - watchdog timeout interrupt.
-
-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>;
