* mfd: Add WM831x AUXADC supportMark Brown2009-09-171-0/+216
The WM831x contains an auxiliary ADC with a number of switchable inputs which is used to monitor some of the voltages and temperatures in the system and has some external inputs which can be used for machine specific purposes. Provide an API allowing drivers to read values from the ADC. An internal reference voltage is provided to allow callibration of the ADC. This is used to calibrate the device at startup. The hardware also supports continuous readings and digital comparators. These are not yet supported by the driver.
