1Kernel driver wm831x-hwmon

14Description
15-----------
16
17The WM831x series of PMICs include an AUXADC which can be used to
18monitor a range of system operating parameters, including the voltages
19of the major supplies within the system. Currently the driver provides
20reporting of all the input values but does not provide any alarms.
21
22Voltage Monitoring
23------------------
24
25Voltages are sampled by a 12 bit ADC. Voltages in milivolts are 1.465
26times the ADC value.
27
28Temperature Monitoring
29----------------------
30
31Temperatures are sampled by a 12 bit ADC. Chip and battery temperatures
32are available. The chip temperature is calculated as:
33
34 Degrees celsius = (512.18 - data) / 1.0983
35
36while the battery temperature calculation will depend on the NTC
37thermistor component.

15-----------
16
17The WM835x series of PMICs include an AUXADC which can be used to
18monitor a range of system operating parameters, including the voltages
19of the major supplies within the system. Currently the driver provides
20simple access to these major supplies.

22Voltage Monitoring
23------------------
24
25Voltages are sampled by a 12 bit ADC. For the internal supplies the ADC
26is referenced to the system VRTC.
