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

26 | Voltage Monitoring | |
27 | ------------------ | |
28 | ||
29 | Voltages are sampled by a 12 bit ADC. For the internal supplies the ADC | |
30 | is referenced to the system VRTC. |
