+description: |
+ The Qualcomm SPMI Round Robin ADC (RRADC) provides interface to clients to read the
+ voltage, current and temperature for supported peripherals such as the battery thermistor
+ die temperature, charger temperature, USB and DC input voltage / current and battery ID
+ resistor.

+ compatible:
+ enum:
+ - qcom,pmi8998-rradc

+ maxItems: 1
+
+ qcom,batt-id-delay-ms:
+ description:
+ Sets the hardware settling time for the battery ID resistor.
+ enum: [0, 1, 4, 12, 20, 40, 60, 80]
