There are ADC ICs which may have some of the AIN pins usable for other

should not be used for ADC.
(Preferred?) way for marking pins which can be used as ADC inputs is to
add corresponding channels@N nodes in the device tree as described in
the ADC binding yaml.
Add couple of helper functions which can be used to retrieve the channel
information from the device node.
I suspect we'll need the addition of an optional trailing timestamp
channel at somepoint. But we can add that when we need it as only
matters for drivers doing iio_push_to_buffers_with_timestamp()
This is true. That'll enable using this for devices with buffers - which
is not possible right now as most buffer users do timestamps. I'll leave
adding the parameter to first buffered user though, but I think it's
good to say out loud this is doable :) Thanks!
Otherwise no additional comments from me.
