Looks good to me. I'd ideally like Lorenzo of someone else to give it
a sanity check. However, I confident enough to add it to the branch
that gets pushed out for build tests in the meantime.
Applied to the togreg branch of iio.git and pushed out as testing for
the autobuilders to play with it.
Thanks,
Jonathan
