  11. Description
  12. -----------
  13. The WM835x series of PMICs include an AUXADC which can be used to
  14. monitor a range of system operating parameters, including the voltages
  15. of the major supplies within the system. Currently the driver provides
  16. simple access to these major supplies.
  17. Voltage Monitoring
  18. ------------------
  19. Voltages are sampled by a 12 bit ADC. For the internal supplies the ADC
  20. is referenced to the system VRTC.
