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. --- adi,high-z-input: type: boolean 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 set= tling requirements of the switched capacitor SAR ADC inputs.
