can't you have different IRQs for each pad ? I mean, allocate one
irq_desc for each pad and let drivers request a pad/pin as an IRQ
source. Then, when you detect a pad wakeup, you can:

unsigned	pad_irq = pad_number - pad->irq_base;

handle_nested_thread(pad_irq);

this will make use of threaded IRQ handlers even. Could it be something
like that ?
