0013 This ADC is often used to provide channels via the io-channels
0014 consumer framework.
0015 Channels list:
0016 0 battery type
0017 1 battery temp NTC (optional current source)
0018 2 GP
0019 3 temp (with ext. diode, optional current source)
0020 4 GP
0021 5 GP
0022 6 VBAT_SENSE
0023 7 VCC_SENSE
0024 8 Backup Battery voltage
0025 9 external charger (VCHG)
0026 10 VBUS
0027 11 DC-DC current probe (how does this work?)
0028 12 internal die temp
0029 13 internal die temp
0030 14 USB ID pin voltage
0031 15 test network
