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. properties: compatible: items: - enum: - qcom,pm8226-iadc - qcom,pm8941-iadc - const: qcom,spmi-iadc reg: description: IADC base address in the SPMI PMIC register map maxItems: 1 qcom,external-resistor-micro-ohms: description: Sensor resistor value.
