7 title: Qualcomm's SPMI PMIC current ADC
10 - Jonathan Cameron <jic23@kernel.org>
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.

27 qcom,external-resistor-micro-ohms:
29 Sensor resistor value. If not defined value of 10000 micro Ohms
35 End of conversion interrupt.
