  Bindings for the max1241 12-bit, single-channel ADC device. Datasheet
  can be found at:
    https://datasheets.maximintegrated.com/en/ds/MAX1240-MAX1241.pdf

properties:
  compatible:
    enum:
      - maxim,max1241

  reg:
    maxItems: 1

  vdd-supply:
    description:
      Device tree identifier of the regulator that powers the ADC.

  vref-supply:
    description:
      Device tree identifier of the regulator that provides the external
      reference voltage.

  shutdown-gpios:
    description:
      GPIO spec for the GPIO pin connected to the ADC's /SHDN pin. If
      specified, the /SHDN pin will be asserted between conversions,
      thus enabling power-down mode.
