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.

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.
Best regards,
