Authors: Mark Brown <>


The WM835x series of PMICs include an AUXADC which can be used to monitor a range of system operating parameters, including the voltages of the major supplies within the system. Currently the driver provides simple access to these major supplies.

Voltage Monitoring

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