> For the WDT callback I think the clearer way is adding a paramter `cb_time` to `wdt_setup_reboot_with_callback()`. This will make the api clearer for all use cases.

Well, that time is fixed on a couple of architectures I looked at. Maybe rather go with a define here?

We should make sure that applications time the warning callback so that the warning is issued at the watchdog timeout, and the reboot is ```WDT_WARNING_PERIOD``` after. Or the other way around. Just consistent. :)

When a callback is set, what happens if a minimum is set and then the wdt is kicked too early?
