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.
On top of https://patchwork.ozlabs.org/patch/1242772/ . Stefan, something like 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.
