The Lenovo SE10 Gen 2 platform uses a watchdog chip from the same family.
Watchdog functionality is the same, so update the driver with the new chip
ID.
Add the Gen 2 MTM's to enable support on the platform.
Tested on SE10 G2.

... but you might want to have a look at the AI review.
It appears that the driver has some issues.

Thanks for the review.
Ack on the AI review patch - thanks for flagging that as I was unaware of those (I'd heard about sashiko.dev - but hadn't thought to check it for results).
It looks like a valid/good thing to fix. I assume it's OK if I push that as a separate patch rather than combining it with this?
Mark

Yes, please.
I updated Sashiko's configuration to reply directly to the author
and to the mailing list for watchdog patches, so going forward you
(and everyone on the list) will get its feedback on watchdog patches
by e-mail.
Thanks,
