| Description |
| ----------- |
| |
| The WM835x series of PMICs include an AUXADC which can be used to |
| monitor a range of system operating parameters, including the voltages |
| of the major supplies within the system. Currently the driver provides |
| simple access to these major supplies. |
| |
| Voltage Monitoring |
| ------------------ |
| |
| Voltages are sampled by a 12 bit ADC. For the internal supplies the ADC |
| is referenced to the system VRTC. |
