  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.
