I said I'll go through it, but it seems the IIO changed again, so I'll need to 
wrap my head around new stuff in there.

Besides, I have a feeling that the driver, as is, just simply doesn't fit in as 
it should. I'm discussing with Jonathan, since I can't really make heads or 
tails from the IIO api. It's way too complex and unless I really missed 
something, way underdocumented.
