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.
