description:
  The GE HealthCare PMC ADC is a 16-Channel (voltage and current), 16-Bit ADC
  with an I2C Interface.

properties:
  compatible:
    const: gehc,pmc-adc

  reg:
    maxItems: 1

  vdd-supply:
    description:
      Regulator for the VDD power supply.

  vdda-supply:
    description:
      Regulator for the VDD analog (VDDA) power supply.

  vddio-supply:
    description:
      Regulator for the VDD IO (VDDIO) power supply.

  vref-supply:
    description:
      Regulator for the voltage reference power supply.

  clocks:
    maxItems: 1
    description:
      The component uses an external oscillator (osc) if an external oscillator
      is connected to its clock pins. Otherwise, it uses an internal reference
      clock.

  clock-names:
    items:
      - const: osc

  "#io-channel-cells":
    const: 2
    description: |
      The first cell is the channel type (dt-bindings/iio/adc/gehc,pmc-adc.h
      defines these values):
       - 0: voltage
       - 1: current
      The second cell is the channel number from 0 to 15.
