+description: |
+ This ADC is often used to provide channels via the io-channels
+ consumer framework.
+ Channels list:
+ 0 battery type
+ 1 battery temp NTC (optional current source)
+ 2 GP
+ 3 temp (with ext. diode, optional current source)
+ 4 GP
+ 5 GP
+ 6 VBAT_SENSE
+ 7 VCC_SENSE
+ 8 Backup Battery voltage
+ 9 external charger (VCHG)
+ 10 VBUS
+ 11 DC-DC current probe (how does this work?)
+ 12 internal die temp
+ 13 internal die temp
+ 14 USB ID pin voltage
+ 15 test network
