And was the first to provide it:

I think all should? As it would be nice/more consistent for all

new version of wdt977 in patch does provide WDIOC_SETTIMEOUT

Personally I'm undecided whether param or ioctl is preferable.

I don't think many would need to change the timeout parameter
at runtime, but if you do it's a pain to reload the module,
so I vote for providing both interfaces?

What about the following though?

cpwatchdog.c
riowatchdog.c
sbc60xxwdt.c

Actually I think there should be a drivers/char/watchdog directory ?
(there are now around 18 seperate watchdog drivers).
Then the out of date watchdog.txt could be updated to point users
at this directory to see what's available, rather than the current
out of date list:

ICS WDT501-P
ICS WDT501-P (no fan tachometer)
ICS WDT500-P
Software Only
SA1100 Internal Watchdog
Berkshire Products PC Watchdog Revision A & C (by Ken Hollis)

ALso I've drivers here for {IBASE, Portwell} SBC watchdogs.
[Who] will I submit them to?

cheers,
Padraig.
