Hi Steve,
Since the interrupt is optional, the driver should also not fail to load
if no interrupt is assigned to it in the first place.
On a separate note, there was a comment stating that the da9062 watchdog is
identical to the da9063 watchdog. If so, why can't you just use the da9063
watchdog driver ?
Thanks,
Guenter
