  13   QPNP PMIC current ADC (IADC) provides interface to clients to read current.
  14   A 16 bit ADC is used for current measurements. IADC can measure the current
  15   through an external resistor (channel 1) or internal (built-in) resistor
  16   (channel 0). When using an external resistor it is to be described by
  17   qcom,external-resistor-micro-ohms property.
