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.
