Hi there, As Drew mentioned, I worked on a driver for eCAP support last summer. I submitted a preliminary patch to mainline Linux for this driver and received some feedback. Unfortunately, around that time, my classes started again and things got very busy so I have not yet had a chance to implement the requested changes. However, the driver itself is fully functional -- the feedback mostly centered around formatting / adopting newer Linux IIO standards. I hope that the driver code is still useful. Please feel free to reach out to me if you have any questions about it.
