the watchdog is pinged within a certain time, this time is called the
timeout or margin. The simplest way to ping the watchdog is to write
some data to the device. So a very simple watchdog daemon would look

like this source file: see samples/watchdog/watchdog-simple.c
A more advanced driver could for example check that a HTTP server is
