6 - compatible: must be "atmel,at91sam9260-wdt".
7 - reg: physical base address of the controller and length of memory mapped
9 - clocks: phandle to input clock.
12 - timeout-sec: contains the watchdog timeout in seconds.
13 - interrupts : Should contain WDT interrupt.
14 - atmel,max-heartbeat-sec : Should contain the maximum heartbeat value in
17 - atmel,min-heartbeat-sec : Should contain the minimum heartbeat value in
18 seconds. This value must be smaller than the max-heartbeat-sec value.
20 - atmel,watchdog-type : Should be "hardware" or "software". Hardware watchdog
