I did a number of searches and found that in the recent kernels the twl4030-madc module has been made upstream.
And I found this link:
http://wiki.gumstix.org/index.php?title=ADC_overo_2.6.39%2B
as I followed it, I couldn't find the directories mentioned therein..

The most relevant thing I found in Linaro-Alip/Nano file system was the /sys/class/i2c-adapter/ folder. Now i'm into the wild and searching for the file I need, so that I can read the ADC values.

Any help meanwhile....???
