Took a peek at the IIO drivers, looks simple enough, so I suggest to drop this 
patch and I'll create an IIO driver instead.

The ltc2485 (as suggested by Guenter on that other thread) is pretty similar 
indeed, it might be feasible to join the two and have one driver handle them 
both. That would be preferred over a separat driver, right?
