IIO device, channel and attribute descriptions


I have a zynq-adrv9364-z7020 board in combination with a ADRV1CRR-BOB.

I've been experimenting with the iio driver and have a question regarding where I can find information about what the devices found actually are and that the channels and they're attributes represent.

For example I can imagine (from the name) that iio:device1: ad7291-bob has something to do with the bob board. Yet nowhere have I been able to confirm this through any documentation. Furthermore have yet to find any information on what for example the channel "voltage6" for this device refers to.

For something like the iio:device2: ad9361-phy (which I think is the iio interface to the AD9364 chip) it would be good to have some documentation on what the values for, for instance, the sampling_frequency_available value attribute actually represent.
