1 * Atmel Watchdog Timers
6 - compatible: must be "atmel,at91sam9260-wdt".
7 - reg: physical base address of the controller and length of memory mapped
11 - timeout-sec: contains the watchdog timeout in seconds.
12 - interrupts : Should contain WDT interrupt.
13 - atmel,max-heartbeat-sec : Should contain the maximum heartbeat value in
14 seconds. This value should be less or equal to 16. It is used to
15 compute the WDV field.
16 - atmel,min-heartbeat-sec : Should contain the minimum heartbeat value in
17 seconds. This value must be smaller than the max-heartbeat-sec value.
18 It is used to compute the WDD field.
19 - atmel,watchdog-type : Should be "hardware" or "software". Hardware watchdog
20 use the at91 watchdog reset. Software watchdog use the watchdog
21 interrupt to trigger a software reset.
22 - atmel,reset-type : Should be "proc" or "all".
23 "all" : assert peripherals and processor reset signals
24 "proc" : assert the processor reset signal
25 This is valid only when using "hardware" watchdog.
26 - atmel,disable : Should be present if you want to disable the watchdog.
27 - atmel,idle-halt : Should be present if you want to stop the watchdog when
29 - atmel,dbg-halt : Should be present if you want to stop the watchdog when
