The watchdog driver wants to set the watchdog timeout in ms and not in ticks, add a method converting ms to ticks before setting the watchdog register. Return the ticks or millisecond the timer was set to in case the provided value was bigger than the max allowed value. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.
