IADC can measure the current15 through an external resistor (channel 1) or internal (built-in) resistor16 (channel 0). When using an external resistor it is to be described by17 qcom,external-resistor-micro-ohms property.18 19properties:20 compatible:21 items:22 - enum:23 - qcom,pm8226-iadc24 - qcom,pm8941-iadc25 - const: qcom,spmi-iadc26 27 reg:28 description: IADC base address in the SPMI PMIC register map29 maxItems: 130 31 qcom,external-resistor-micro-ohms:32 description:33 Sensor resistor value.
