   13   This ADC is often used to provide channels via the io-channels
   14   consumer framework.
   15   Channels list:
   16     0 battery type
   17     1 battery temp NTC (optional current source)
   18     2 GP
   19     3 temp (with ext. diode, optional current source)
   20     4 GP
   21     5 GP
   22     6 VBAT_SENSE
   23     7 VCC_SENSE
   24     8 Backup Battery voltage
   25     9 external charger (VCHG)
   26     10 VBUS
   27     11 DC-DC current probe (how does this work?)
   28     12 internal die temp
   29     13 internal die temp
   30     14 USB ID pin voltage
   31     15 test network
