watchdog: WatchDog Timer Driver Core - Part 1
The WatchDog Timer Driver Core is a framework
that contains the common code for all watchdog-driver's.
It also introduces a watchdog device structure and the
operations that go with it.
This is the introduction of this framework. This part
supports the minimal watchdog userspace API (or with
other words: the functionality to use /dev/watchdog's
open, release and write functionality as defined in
the simplest watchdog API). Extra functionality will
follow in the next set of patches.
Have you thought about callback support for systems that support a
two-stage watchdog? That way we could do something useful (preserve
system memory using kdump, for instance) rather than just getting
whacked by the hardware.
