[Q] Touchscreen drivers location? topic

Hey guys,

Im trying to port a I9505 rom to my I9515 but one of the main problems is that the touchscreen doesn't work when you flash I9505 roms on the I9515. So I went looking for the touchscreen drivers in a stock rom but I just can't find them. So do you guys have any idea where the touchscreen drivers are located?

Thanks.
