  channel-count:
    type: int
    required: true
    description: The maximum channels supported on each unit.

  vref-mv:
    type: int
    required: true
    description: Indicates the reference voltage of the ADC in mV (on the target board).

  resolution:
    type: int
    required: true
    description: Indicates the resolution supported by the ADC instance.

  clock-source:
    required: true
    type: int
    enum: [0, 1, 2, 3]
    description: |
      Clock source to be used by the ADC peripheral. The following options
      are available:
      - 0: "ADI_MAX32_PRPH_CLK_SRC_PCLK" Peripheral clock
      - 1: "ADI_MAX32_PRPH_CLK_SRC_EXTCLK" External Clock
      - 2: "ADI_MAX32_PRPH_CLK_SRC_IBRO" Internal Baud Rate Oscillator
      - 3: "ADI_MAX32_PRPH_CLK_SRC_ERFO" External Radio Frequency Oscillator
      The target device might not support every option please take a look on
      target device user guide

  clock-divider:
    required: true
    type: int
    enum: [1, 2, 4, 8, 16]
    description: |
      The clock divider divides the ADC source clock to set the ADC clock frequency as follows:
        F_sar_clk = F_clock_source / clock divider

  track-count:
    required: true
    type: int
    description: |
      The number of cycles to add to the minimum track time.

  idle-count:
    required: true
    type: int
    description: |
      The number of cycles to add to the minimum hold time.
