Description
|
|
-----------
|
|
|
|
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.
