hmm, iio_map stuff looks nice, so before messing with devicetree,
I could solve 90% of the problem by just using iio_map? For my use
cases it is enough to have the internal stuff at the moment. That would
simplify stuff a lot.

So I could go forward with the iio_map stuff now, and if there is a use
case for AIN1/0, the devicetree stuff can be added later?

Regards,
Andreas
