My feeling is that this should go with the v4l subsystem thus Cc-ing linux-media. Do you have any datasheet for this sensor? At some point [1] we considered introducing the fingerprint sensor as an IIO device, but that didn't quite fit. So, we reconsidered using v4l. I this is your case too :). Hope this helps. Daniel.
