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. |
