| 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. |

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