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
