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.
