|  | 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. |
