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.
