+         ARM SBSA Generic Watchdog has two stage timeouts:
+         the first signal (WS0) is for alerting the system by interrupt,

+         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
