Can you tell me what you tested? Was it the software debounce?
Because this should be the only bit that will affect the ath79
platform I think (since it already has support for interrupts
through the gpio controller).

From what I can tell, ramips should use gpio-keys-polled exclusivly
for now. This is because the rt2880-pinmux driver doesn't implement
and irq support (though some of the chips should support it).
all gpio-keys-polled should work as before.
 
Cheers,
Christian
