Hello Lars. Thank you for your interest and sorry for the late answer. When I posted the proposal I was still studying the event interface, so I decided not to add it as a possible use case yet. I believe an input abstracted evdev would allow the creation of a more flexible and simpler to use event interface. Every event generated by a device could be broadcasted trough a single file in /dev (created by the abstracted evdev) and read by an application with the help of an header file describing the new event interface (like input currently does with evdev and input.h). This approach will allow to have an event interface that's simpler to use for an userspace app because instead of reading N sysfs files concurrently the app will have to read just one file in /dev and then handle the events received with something like a switch statement. Input abstracted evdev will help by creating the /dev file and forwarding the file_operations on that file to iio. I have added a bit more detailed explanations on my proposal. This is just an idea, I'm looking for your feedbacks to make it better.
