as Jonathan knows, i was one of main authors of those drivers in

so to push iio ahead, we might push related app ahead too.

Well, that's not entirely clear - one of the reasons for discussing an
in kernel API is so that drivers for these subsystems can make use of
IIO channels.  Another big blocker for deployment of IIO right now is
that it's in staging, fixing that will probably help enormously.
