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