Step configuration enable and the order in which touchscreen expects positive / negative terminals to be connected to analog inputs lines was hard coded. Now the user can provide platform data to represent the same.
Also only fine tuning variance in tslib utility to remove ADC noise does not help. Hence adding logic to eliminate ADC noise and unwanted random signals. This patch set is dependent on [1] and has been tested on AM335x EVM.
