The current watchdog API suggests that the pretimeout "allows Linux
to record useful information (like panic information and kernel
coredumps) before it resets". The call to panic() would be the
means to make this happen.

Now that I think about it, that does make sense.

However, if a pre-timeout is not set, then the driver should never call
panic().  That means that the interrupt handler should only be registered if
sbsa_gwdt_set_pretimeout() is called.

I don't know why you want to do this tricky way.  you can always
register the interrupt handler,
if pre-timeout is 0, system will just trigger WS1 right after WS0
