Hi,
I just hit a problem with the accelerated (interrupt driven) ts driver. It
stop responding after a while (sometimes right after you release a stylus off
the touchscreen, it doesn't generate any more interrupts). I made the
following patch that fixes the problem for me (and if I read the 9712 and
9713 manuals correctly, the patch should be OK)
Thanks for reply.
