[PATCH 0/3] watchdog: honour hw_margin_ms property

[Rasmus Villemoes]

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? 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.

Rasmus Villemoes (3):
  watchdog: remove stale ifndef CONFIG_WATCHDOG_TIMEOUT_MSECS from wdt.h
  watchdog: move initr_watchdog() to wdt-uclass.c
  watchdog: honour hw_margin_ms DT property
