15 | ----------- | ||
16 | |||
17 | The WM835x 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 | simple access to these major supplies. | ||

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