  18 Description
  19 -----------
  20
  21 The WM835x series of PMICs include an AUXADC which can be used to
  22 monitor a range of system operating parameters, including the voltages
  23 of the major supplies within the system.  Currently the driver provides
  24 simple access to these major supplies.

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