From: "Mathieu A.-Tetreault" <[email protected]> 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.
