Some watchdogs must be reset more often than the once-per-second ratelimit used by the generic watchdog_reset function in wdt-uclass.c. There's precedent (from the gpio-wdt driver in linux) for using a property called hw_margin_ms to let the device tree tell the driver how often the device needs resetting. So use that generically. No change in default behaviour.

Stefan, something like this?
Yes, thanks for looking into this.
That at least solves half my problems and might be useful to others as well. Then I'll have to figure out the time-stands-still problem in some other way.
If its too hard to enable interrupts in SPL for you or to provide some other means of a working get_timer() API, then we needto find another solution. You started with this weak function, which of course works. What other options are there? Adding a callback mechanism to register platform specific callback functions? Even though this might get a little bit too complicated.
Thanks, Stefan
