| 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). |
| 14 | |
| 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>; |
| 24 | }; |
