You don't need to describe the channels in devicetree, except setting the

node.

Aha. So right now I do have in my device tree:

       adc {
               ti,adc-channels = <4>;
       };

for the producer ADC node. But this seems wrong. Correct would be


       adctsc: adc {
               ti,adc-channels = <4>;
               #io-channel-cells = <1>;
       };

And the consumer can then specify everything. This seems to be looking
good. And with this the map piece can die.
Thanks.

After that it's just a matter of using, e.g.

	io-channels = <&adc 1>;
	io-channel-names = "voltage";

in your consumer.
