Good point, let's match adc.yaml and use 'channel' instead.  I'll
respin this series with thas, as well as rebasing on -next to solve
conflicts with 8013295662f5 ("arm64: dts: qcom: sc8280xp: Add label
property to vadc channel nodes"): supposedly that DT originally relied
on the `@XX` suffix bug :)

Should it inherit the common binding, or was it omitted for a reason?
