Yeah, sorry about that - people keep wanting new stuff ;)

Any documentation writers welcome!
The real trick currently is to
a) figure out what is similar an already present
b) figure out if that driver is actually a good starting point. If it's
left staging then it's clean, but there may be a closer 'clean' driver
still in staging.

Having had documentation continually get left behind we did add
a 'dummy' driver that covers most stuff with lots of comments.
(still in staging at the mo staging/iio/iio_simple_dummy*)
