I don't think we need to do both count and interval and you don't
 really need to track state... What do you think about the patch below?

I would say it's pretty different from what I meant. You patch only
delays the decision about the status of the pin while mine does really
"average" the status
of the pin. E.g. in my tosa PDA the headphones jack is a bit noisy. So
the input layer shouldn't react to the noise. And with your patch each
time the GPIO irq is generated the input layer will get input_sync.
