The changes are seems to be OK. Can you please add some debugging printk in the driver/input/touchscreen/ads7846.c driver?
yes, can you tell me what I have to print? only function calls or also variable values?
Please add printk to show the value of x, y, before and after the OMAP3EVM macro. That will give better idea about the touchevent.
NOTE: Please always CC to the list. So that, you may get better tips from other members.
Bye :)
I noticed that lines in logcat
I/EventHub( 1070): New device: path=/dev/input/event0 name=ADS7846 Touchscreen id=0x20001 (of 0x2) index=2 fd=86 classes=0x4 I/InputReader( 1070): Device added: id=0x20001, name=ADS7846 Touchscreen, sources=00001002 I/InputManager-Callbacks( 1070): No input device calibration properties found for device ADS7846 Touchscreen.

I'm sorry, where is the OMAP3EVM macro?
Thanks Francesco

Oops. I hope, it is in EVM Code. For BB-xM, it might be different.
The following set of commands are responsible for sending the co-ordinates to user space. You have to add printk before this and check.
input_report_abs(input, ABS_X, x); input_report_abs(input, ABS_Y, y); input_report_abs(input, ABS_PRESSURE, ts->pressure_max - Rt);
Can you share info about code base (Rowboat/Linaro) ?
Bye :)
