Applied to the togreg branch of iio.git.
Out of curiosity, do you actually have one of these?
At a quick glance, the only remaining bit keeping this driver
in staging is the lack of docs on the infrared_supression
attribute. If you want to add something on that and a patch
moving it out of staging that would be great.
However, note that the graduation patch is usually the one
that gets the driver thoroughly reviewed by several people so
more stuff may come out of the woodwork.
Thanks,
Jonathan
