| 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. |
