description: >
  Calibration coefficients for the soil sensing circuit. We have two polynomials whose input variable
  is the battery voltage in Volts. The evaluated polynomial corresponds to the estimated ADC value,
  assumed to be 10 bits, so in [0, 1024). The two polynomials are:
    dry: For estimation of the fully dry state, given the battery voltage
    wet: For estimation of the fully dry state, given the battery voltage

  Note that each poly coefficient is specified as 1000 times its real values. This is because we can't
  directly represent floating points in devicetree. The final evaludated value should be divided by
  1000.0f in code.
