Hi,
I have managed to get xinput detect the ADS7846 touchscreen detection on the beagle board.
Here are the mux settings:
etk_d0 - mode: OMAP_PIN_OUTPUT | OMAP_MUX_MODE1
etk_d1 - mode: OMAP_PIN_INPUT | OMAP_MUX_MODE1
etk_d2 - mode: OMAP_PIN_OUTPUT | OMAP_MUX_MODE1
etk_d3 - mode: OMAP_PIN_OUTPUT | OMAP_MUX_MODE1
Perhaps there is problem in configuring. Currently the touchscreen is not responding. The /var/log/Xorg.0.log shows:

If i do cat /dev/input/event0 or cat /dev/input/mouse0, there is not output upon tapping the touchscreen.
Any pointers on this would be of great help.
