If you plan to support that functionality at somepoint make sure to define dt bindings and similar to specify which channels are enabled and dynamically create the iio_chan_spec array to match. It can be a bit ugly to retrofit later. Oh. It does daisy chaining as well. That is always fun to support though I guess you may well not have it wired up to do that. Oversampling as well - though that looks nice and simple for once. Jonathan > > [1] https://www.ti.com/product/ADS7066 > >
