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.
