I tried a little bit with your driver. The disadvantage I see is, its claims 
all the free AD channels. But a few of them can also act as a touchscreen 
controller. Shouldn't be the driver handle the channel usage dynamically? 
Also this AD module on the SoC can measure the die temperature, battery 
voltage and some other power supplies.
I see more than one framework this driver should connect to: simple ADC (IIO), 
touchscreen controller (INPUT), die temp (POWER?), various voltages (POWER? 
REGULATOR?). Should it be a multi function device?
