Yeah, let's put 'Wrapper' in the crapper. Not married to it.
Miscellaneous?
So, not super-happy about that either. And maybe leave the mux
where it is? It's just that I have the feeling that the iio-mux
is never going to get any friends in its category, and the mux
and the unit-converter are kind of related in that they operate
on other channels. But maybe that's only logical it you know how
they are implemented...
