I don't think we've defined 'adc-chan' as THE generic name. Looks like we have: adc-chan adc-channel channel 'channel' is the most common (except for QCom). Rob

Harmless but little point as far as I can see given we don't happen to have any of the generic elements defined in the generic channel binding. Jonathan > > - Marijn >

Supposedly the reg property, and now also the node name. Up to you to say whether I should inherit this (and strip out the common bits) or just focus on renaming the node name in the existing binding to channel. - Marijn

Update the example to reflect a future requirement for the generic adc-chan node name on ADC channel nodes, while conveying the board name of the channel in a label instead.
