|
|
- clocks : This is pclk (APB clock).
|
|
- interrupts : This is wd_irq - watchdog timeout interrupt.
|
|
- interrupt-parent : Must be core interrupt controller.

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>;
