It is i.mx28 based so it has the mxs LRADC which is currently supported
through drivers/staging/iio/adc/mxs-lradc.c.
It is also a touchscreen controller, a temperature sensor and a battery
voltage monitor so it would make sense to create an mfd and move the
touchscreen part in the input subsystem and add a driver for the voltage
monitor in the power subsystem.

You can also have a look at that thread:
