Thanks elu_digi for the reply. My touchcreen is connected to the port designated as LCD1.
But i had a different issue. I was unable to integrated touchscreen with X. Touchpad was working fine. I tried configuring touchscreen with evdev, evtouch.
I have now configured the touchscreen.
I build and installed tslib and xf86-input-tslib for arm.
