Just want to add that this is a 'misc' device and this option is still on
the table. If you think the standard IIO ABI is too restrictive and you'd
rather have a device specific ABI you can write a misc driver for your
device. Or directly write a userspace driver.

The preferred solution of course is to work with the IIO framework and come
up with solutions for the shortcomings.
