I missed one...

I also think it makes sense for the High-Z mode selection to be a DT
property since needing to enable it or disable it depends entirely on
what is connected to the analog input pins.

    description:
      High-Z mode allows the amplifier and RC filter in front of the ADC to be
      chosen based on the signal bandwidth of interest, rather than the settling
      requirements of the switched capacitor SAR ADC inputs.
