Ok, finally I found some time. In general, the patch works fine. The
only detail I had to amend was the irqflags, which were changed from
IRQF_TRIGGER_RISING/IRQF_TRIGGER_FALLING to
IRQF_TRIGGER_HIGH/IRQF_TRIGGER_LOW, which doesn't work as the PXA can't
deal with level-based IRQs. Changing this back to RISING/FALLING makes
the driver work again.
Hmm, but that would mean we need to restore reading the data in open()
to make sure we re-arm IRQ in case somebody touched the screen before it
was opened by userspace...
Hmm, right, that was the reason why I put it there in the first place.
Thanks for the heads-up. Would you do it? Want me to?
