I can see /dev/iio:device0 and /sys/bus/iio/devices/iio:device0 when I use the ADF5355 driver.
As documented, /sys/bus/iio/devices/iio:device0 provides two channels for outputs a & b for changing frequency, power up and down the two channels.
Is /dev/iio:device0 useful? does it provide any useful interface? Is there any documentation on that?
