| 14 | Description | |
| 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. |
