Driver for the "SMB2" charger block found on Qualcomm PMI8998
and PM660 PMICs.
The charger features automatic power source detection via BC1.2,
automatic input current limiting and reports the realtime voltage
and current via the Round Robin ADC.
Say Y or M here to enable reporting the charger status and rate on
supported platforms such as Snapdragon 845 and 835 based phones.
