In linux kernel since version 4.1 (release Date: 2015-06-21)
Select this to get support for Allwinner SoCs (A10, A13 and A31) ADC.
This driver will only map the hardware interrupt and registers, you
have to select individual drivers based on this MFD to be able to use
the ADC or the thermal sensor. This will try to probe the ADC driver
sun4i-gpadc-iio and the hwmon driver iio_hwmon.
To compile this driver as a module, choose M here: the module will be
called sun4i-gpadc.
