+description: |
+  SPMI PMIC5 Gen3 voltage ADC (ADC) provides interface to clients to read
+  voltage. It is a 16-bit sigma-delta ADC. It also performs the same thermal
+  monitoring function as the existing ADC_TM devices.
+
+  The interface is implemented on SDAM (Shared Direct Access Memory) peripherals
+  on the master PMIC rather than a dedicated ADC peripheral. The number of PMIC
+  SDAM peripherals allocated for ADC is not correlated with the PMIC used, it is
+  programmed in FW (PBS) and is fixed per SOC, based on the SOC requirements.
+  All boards using a particular (SOC + master PMIC) combination will have the
+  same number of ADC SDAMs supported on that PMIC.
