Kernel driver wm831x-hwmon
==========================

Supported chips:
* Wolfson Microelectronics WM831x PMICs
Prefix: 'wm831x'
Datasheet:
http://www.wolfsonmicro.com/products/WM8310
http://www.wolfsonmicro.com/products/WM8311
http://www.wolfsonmicro.com/products/WM8312

Authors: Mark Brown <[email protected]>

Description
-----------

The WM831x 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
reporting of all the input values but does not provide any alarms.

Voltage Monitoring
------------------

Voltages are sampled by a 12 bit ADC. Voltages in milivolts are 1.465
times the ADC value.

Temperature Monitoring
----------------------

Temperatures are sampled by a 12 bit ADC. Chip and battery temperatures
are available. The chip temperature is calculated as:

Degrees celsius = (512.18 - data) / 1.0983

while the battery temperature calculation will depend on the NTC
thermistor component.

Kernel driver wm8350-hwmon

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.
