Default value is set when compiling the kernel. If it is set
to "Y", then there is no way of disabling the watchdog once
it has been started.
kdumptimeout Minimum timeout in seconds to apply upon receipt of an NMI
before calling panic. (-1) disables the watchdog. When value
is > 0, the timer is reprogrammed with the greater of
value or current timeout value.

watchdog core:
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
fallback logic in the bootloader to try something else.
