I do not have strong opinion about this. Currently we have no
restrictions for the node names:
Documentation/devicetree/bindings/iio/adc/ti,tsc2046.yaml
Documentation/devicetree/bindings/iio/adc/adc.yaml

I can name it touchscreen-adc@0 or something like this. What are your
preferences?

Regards,
Oleksij
