ARM SBSA Generic Watchdog has two stage timeouts: the first signal (WS0) is for alerting the system by interrupt, the second one (WS1) is a real hardware reset. More details: ARM DEN0029B - Server Base System Architecture (SBSA)
This driver can operate ARM SBSA Generic Watchdog as a single stage or a two stages watchdog, it depends on the module parameter "action".
Note: the maximum timeout in the two stages mode is half of that in the single stage mode.
