1Zynq Watchdog Device Tree Bindings
2-------------------------------------------
3
4Required 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
10Optional 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).
14
15Example:
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>;
24 };
