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
