  # selftests: watchdog: run_watchdog-test.sh
  # ./run_watchdog-test.sh: Feed dog
  # Watchdog Ticking Away!
  # ..
  # ./run_watchdog-test.sh: Show watchdog_info
  # watchdog_info:
  #  identity:            iTCO_wdt
  #  firmware_version:    2
  # Support/Status: Set timeout (in seconds)
  # Support/Status: Supports magic close char
  # Support/Status: Keep alive ping reply

  # ./run_watchdog-test.sh Turn off the watchdog timer
  # Watchdog card disabled.
  # Watchdog Ticking Away!
  # ..
  # ./run_watchdog-test.sh: Turn off the watchdog timer
  # Watchdog card enabled.

  # Watchdog card disabled.
  # Watchdog timeout set to 10 seconds.
  # Watchdog card enabled.
  # Watchdog Ticking Away!
  # ..
  # ./run_watchdog-test.sh: Get the timeout
  # WDIOC_GETTIMEOUT returns 10 seconds.
  #
  # ./run_watchdog-test.sh: Get the pretimeout to T seconds
  # Watchdog card disabled.
  # WDIOC_GETPRETIMEOUT returns 0 seconds.
  # Watchdog card enabled.
  #
  # ./run_watchdog-test.sh Get the time left until timer expires
  # WDIOC_GETTIMELEFT returns 9 seconds.
  #
