15 The Texas Instruments TWL4030 is a Power Management and Audio Circuit. Among
16 other things it contains a 10-bit A/D converter MADC. The converter has 16
17 channels which can be used in different modes.
20 See this table for the meaning of the different channels
23 ------------------------------------------
25 1 BCI: Battery temperature (BTEMP)
32 8 BCI: VBUS voltage(VBUS)
33 9 Backup Battery voltage (VBKP)
34 10 BCI: Battery charger current (ICHG)
35 11 BCI: Battery charger voltage (VCHG)
36 12 BCI: Main battery voltage (VBAT)
39 15 VRUSB Supply/Speaker left/Speaker right polarization level
42 The Sysfs nodes will represent the voltage in the units of mV,
43 the temperature channel shows the converted temperature in
44 degree celcius. The Battery charging current channel represents
45 battery charging current in mA.
