The proper way would be to see of IIO doesn't already have some ways to control those (it likely does) and then these would automatically be accessible via sysfs. > Is there any example of how to control a hw-specific feature in other > similar iio drivers? None that I'm aware of, but I didn't look. I suspect this would be somewhere around the channel defitionion, since the /2 function of the LRADC is a per- channel feature on the LRADC.
