Hi Jonathan,

Didn't mean to rush things, I haven't seen any activity on this for
some time and thought it was forgotten. I was also confused with the
status of Mika's patch, but now that I learned it was merged in 4.2,
its clear to me that this patch needs to go through the IIO tree.

Thanks,
Tavi
