Hello Chris,

> The first interrupt is for the regular watchdog timeout. Normally the
> RSTOUT line will trigger a reset before this interrupt fires but on
> systems with a non-standard reset it may still trigger.
>
> The second interrupt is for a timer1 which is used as a pre-timeout for
> the watchdog.

To keep bisectability this patch should be merged after the driver
patch.

Thanks,

Gregory
