Hi,
I'd like to request for comments on the attached driver, which supports
watchdogs on several Winbond super I/O chip models and have been tested
on a few of recent Supermicro motherboards.
Is there any reason this is not yet committed? Please commit, pretty
please.
Yes we have 2+ of them and are trying to merge. The other one sits here
and allows you even longer timeouts as well as time setting the timeout
independent of watchdogd in case you have two watchdogs and want to do tricks
like NMI/reset with the other one... but is lacking the man page yet.
I have added another one or two IC revisions I think that I had found
and tested privately.

I've been using 20110718-02-wbwd.diff for a few months now on a project
with PC Engines Alix 1.d boards (http://pcengines.ch/alix1d.htm). They
have a Winbond W83627HG chip. I don't see any probing/attach messages
on boot but the driver seems to be properly configuring the chip - if I
kill watchdogd with -9 the board reboots with watchdog timeout.
I'm also trying to use the above winbond chip for GPIO (userland bit
banging at this point).
