  ref-supply:
    description:
      Reference Input/Output. The voltage at the REF pin sets the full-scale
      range of all channels. If not provided the internal reference is used and
      also provided on the VREF pin.

  reset-gpios:
    description:
      Active Low Asynchronous Clear Input. A logic low at this level triggered
      input clears the device to the default reset code and output range, which
      is zero-scale with the outputs off. The control registers are cleared to
      zero.
    maxItems: 1

  adi,rfsadj-ohms:
    description:
      If FSADJ is tied to VCC, an internal RFSADJ (20 kΩ) is selected, which
      results in nominal output ranges. When an external resistor of 19 kΩ to
      41 kΩ can be used instead by connecting the resistor between FSADJ and GND
