  14 Description
  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.

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