      Maximum frequencies from datasheet operating requirements.
      Three values necessary to cover the 3 conversion modes.
      * Frequency in normal mode (ADLPC=0, ADHSC=0)
      * Frequency in high-speed mode (ADLPC=0, ADHSC=1)
      * Frequency in low-power mode (ADLPC=1, ADHSC=0)

  min-sample-time:
    $ref: /schemas/types.yaml#/definitions/uint32
    description:
      Minimum sampling time in nanoseconds. This value has
      to be chosen according to the conversion mode and the connected analog
      source resistance (R_as) and capacitance (C_as). Refer the datasheet's
      operating requirements. A safe default across a wide range of R_as and
      C_as as well as conversion modes is 1000ns.
