While looking for efforts to provide a generic driver for gpio driven
watchdog devices, like some simple hardware supervisors, I came into
this patchset RFC, which turned out to be very interesting to me.
Maybe I'm looking into the wrong places, but I could not find any
upstream commit after this RFC.
Since I don't see any real critic from commenters to the approach you
are suggesting, I'd like to know if there still is some
work-in-progress on this.

Kind regards,
