How can we be sure that DT_INST(0, nordic_nrf_adc) is ADC_0? Shouldn't we use DT_NODELABEL() here?

I'm guessing in this case its know that ADC is a singleton, since the driver uses DT_INST.

It was more of a general comment to the conversions performed in this PR. Some of the coversions convert from ADC_1 to DT_INST(0, ...).

If the driver is multi-instance at all, the INST ordering should be assumed to be basically random, so this is indeed an issue in general (though for this particular line of source it's a singleton).

@mbolivar-nordic I might have been a bit too trigger-happy with this one. @henrikbrixandersen please feel free to continue the conversation here and then we can create a separate PR if necessary to tweak whatever is needed.

I personally think the INST conversions should be removed and replaced with either NODELABEL or ALIAS.
Edit: in cases where ambiguity is possible, not this particular line

I'd prefer NODELABEL

or in this case, for a lot of these PATH would make sense since they are board specific ifdefs.

Either NODELABEL or PATH seems fine as way to resolve this issue
