I noticed that for minItems == 1, the rdy interrupt is required and err
is the optional one.

With that in mind, you can simplify the interrupts description so that
it describes the interrupts separately:

  interrupts:
    minItems:
    items:
      - description:
          Ready: multiplexed with SPI data out. While SPI CS is low,
          can be used to indicate the completion of a conversion.

      - description:
          Error: The three error bits in the status register (ADC_ERROR, CRC_ERROR,
          and REG_ERROR) are OR'ed, inverted, and mapped to the ERROR pin. Therefore,
          the ERROR pin indicates that an error has occurred.

Otherwise, I think everything has been sorted out?
