Not sure where this question belongs, but asking here...
We have a couple of ZedBoard/FMComms3/AD9361 evaluation units, with a couple of different software revs on them.
One of them (the newer version, I think) instantiates two adf4351 devices, one for tx and one for rx, as iio:device3 and iio:device4... The other sw version doesn't instantiate these devices at all.
As far as I know these devices don't exist on the FMComms3 board...
What purpose do they serve in using the AD9361 device?
