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. | |
