As per the linux kernel documentation:
 The iTCO v1 and v2's internal timer is stored as ticks which decrement
 every 0.6 seconds.  v3's internal timer is stored as seconds (some
 datasheets incorrectly state 0.6 seconds).

https://github.com/torvalds/linux/blob/master/drivers/watchdog/iTCO_wdt.c#L136

This have been tested on an iTCOv3 board.
