| 18 | Description |
| 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. |
| 25 | |
| 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. |
