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