open_timeout:
Maximum time, in seconds, for which the watchdog framework will take
care of pinging a running hardware watchdog until userspace opens the
corresponding /dev/watchdogN device. A value of 0 means an infinite
timeout. Setting this to a non-zero value can be useful to ensure that
either userspace comes up properly, or the board gets reset and allows

+ stop_on_reboot:
+ Stops watchdogs on reboot (0 = keep watching, 1 = stop).
