0018 Description
0019 -----------
0020 
0021 The WM835x series of PMICs include an AUXADC which can be used to
0022 monitor a range of system operating parameters, including the voltages
0023 of the major supplies within the system.  Currently the driver provides
0024 simple access to these major supplies.

0026 Voltage Monitoring
0027 ------------------
0028 
0029 Voltages are sampled by a 12 bit ADC.  For the internal supplies the ADC
0030 is referenced to the system VRTC.
