Hi Shinji,

Are you aware of the counter subsystem that has been proposed (and
as far as I am concerned is ready to be merged)?

https://patchwork.kernel.org/project/linux-iio/list/?series=147
(I think that's the latest version posted)..
William, perhaps you could give an update?

(bad luck, you are getting popular ;)

I'll take a quick review as it stands, as some issues may carry over.
I appreciate that it's always unfortunate to try to upstream stuff at the
same time as a new framework is being developed / upstreamed, but I don't
intend to take any additional counter drivers into IIO.  We just
end up having to maintain old interfaces in more and more drivers.

Thanks,

Jonathan
