  adi,internal-ref-microvolt:
    description: |
      Internal reference voltage selection in microvolts.

      If no internal reference is specified, the channel will default to the
      external reference defined by vrefin-supply (or vref-supply).
      vrefin-supply will take precedence over vref-supply if both are defined.

      If no supplies are defined, the reference selection will default to
      4096mV internal reference.
