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>;
};
