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. 18 19properties: 20 compatible: 21 items: 22 - enum: 23 - qcom,pm8226-iadc 24 - qcom,pm8941-iadc 25 - const: qcom,spmi-iadc 26 27 reg: 28 description: IADC base address and length in the SPMI PMIC register map 29 maxItems: 1 30 31 qcom,external-resistor-micro-ohms: 32 description: 33 Sensor resistor value.
