properties:
  unit-id:
    type: int
    required: true
    description: |
      The ADC unit, defined by adc_unit_t (e.g. ADC_UNIT_1, ADC_UNIT_2).
  clk-src:
    type: int
    default: 0
    description: |
      Clock source, defined by adc_oneshot_clk_src_t. 0 selects the default clock source.
  ulp-mode:
    type: int
    default: 0
    description: |
      ULP control mode, defined by adc_ulp_mode_t. 0 means ADC_ULP_MODE_DISABLE.
  channels:
    type: phandle-array
    element-type: "struct Esp32AdcOneshotChannelConfig"
    default: "{ }"
    description: |
      Per-channel configuration. Each entry is written as <channel atten bitwidth>,
      e.g. <ADC_CHANNEL_3 ADC_ATTEN_DB_12 ADC_BITWIDTH_DEFAULT>.
      A consumer device refers to a channel with a phandle and channel number, e.g. `<&adc0 3>`.
