I'm a little confused about what the "io-channel-ranges" does here.
The documentation isn't clear at all to me for it. If I'm reading it
right it's also supposed to be for iio-consumers, but you're using it
in a provider. I see you copied this from the example. Maybe the
example is wrong? ...or I'm just confused...
Other than that question, this looks fine to me.
