+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.

+  reg:
+    maxItems: 1
