   4 Required properties:
   5 - compatible            : Should be "cdns,wdt-r1p2".
   6 - clocks                : This is pclk (APB clock).
   7 - interrupts            : This is wd_irq - watchdog timeout interrupt.
   8 - interrupt-parent      : Must be core interrupt controller.
   9
  10 Optional properties
  11 - reset-on-timeout      : If this property exists, then a reset is done
  12                           when watchdog times out.
  13 - timeout-sec           : Watchdog timeout value (in seconds).

  15 Example:
  16         watchdog@f8005000 {
  17                 compatible = "cdns,wdt-r1p2";
  18                 clocks = <&clkc 45>;
  19                 interrupt-parent = <&intc>;
  20                 interrupts = <0 9 1>;
  21                 reg = <0xf8005000 0x1000>;
  22                 reset-on-timeout;
  23                 timeout-sec = <10>;
