Ram, thanks again for your quick response. I have tried to recompile the tslib with the changes for the event type reporting. I say "tried" because I am not sure if it worked because the results are still the same. Getting zeros for all touch event.
I am working on an OMAP4430 board, but in principle the touch screen is the same. I use the Pengutronix dist as provided by Phytec. I entered the source directory and edited the tslib file input-raw.c file with the changes you suggested.
Is there a way to get the version of the tslib from the target device os?
Also, note that I am not particularly interested in multitouch as such, single touch would also be ok.
I have add prints in your driver to display the received touch info, and touch point one indicates correct values when touching the screen, so hardware and driver/irq installation is fine.
Thanks for your help.
