Hello, I'm in the process of adding a new IIO/counter driver, however I also saw that there was a work in progress to have a separate counter subsystem ( https://marc.info/?l=linux-iio&m=153974167727206 ). But it seems there is no recent progress on it. What is the state of those patches ? Is it still interesting to develop the driver as an IIO/counter , or should I use already that new subsystem ? Best Regards, Patrick Havelange.
