looks like am not getting the touchscreen interrupts.
i havent even calibrated my touchscreen. but i have enabled the SPI
interface and the ADS7846 touchscreen in the kernel. could you tell me
how to calibrate it or make it work? i guess i am missing out on some
files like i have nothing like ts_calibrate in my filesystem.
thank you,
regards,
Shareef
