description: |
  The ADS131M0x are a family of multichannel, simultaneous sampling,
  24-bit, delta-sigma, analog-to-digital converters (ADCs) with a
  built-in programmable gain amplifier (PGA) and internal reference.
  Communication with the ADC chip is via SPI.

  clocks:
    description:
      Phandle to the external clock source required by the ADC's CLKIN pin.
      The datasheet recommends specific frequencies based on the desired power
      mode (e.g., 8.192 MHz for High-Resolution mode).
