15 -----------
26 Channel 0 VDDOUT - measurement of the system voltage
27 Channel 1 ICH - internal battery charger current measurement
28 Channel 2 TBAT - output from the battery NTC
29 Channel 3 VBAT - measurement of the battery voltage
30 Channel 4 ADC_IN4 - high impedance input (0 - 2.5V)
31 Channel 5 ADC_IN5 - high impedance input (0 - 2.5V)
32 Channel 6 ADC_IN6 - high impedance input (0 - 2.5V)
33 Channel 7 XY - TSI interface to measure the X and Y voltage of the touch
35 Channel 8 Internal Tjunc. - sense (internal temp. sensor)
36 Channel 9 VBBAT - measurement of the backup battery voltage
39 By using sysfs attributes we can measure the system voltage VDDOUT, the battery
40 charging current ICH, battery temperature TBAT, battery junction temperature
41 TJUNC, battery voltage VBAT and the back up battery voltage VBBAT.
44 ------------------
48 The battery voltage is calculated as:
52 The backup battery voltage is calculated as:
60 Temperature Monitoring
61 ----------------------
63 Temperatures are sampled by a 10 bit ADC. Junction and battery temperatures
66 The junction temperature is calculated:
68 Degrees celsius = 1.708 * (TJUNC_RES - T_OFFSET) - 108.8
70 The junction temperature attribute is supported by the driver.
72 The battery temperature is calculated:
74 Degree Celsius = 1 / (t1 + 1/298) - 273
78 Default values of R25, B, ITBAT are 10e3, 3380 and 50e-6 respectively.
