Really ?
In out test environment, my test program could detect edge interrupt

My test program used poll/select on edge successfully. But I could not test
the raising or falling feature actually, as my input is bouncing. So, it
doesn't matter if I set both/raising/falling in edge, due to my inputs the
effect is the same. Any input event will end in several raising and falling
interrupts events.
I hope I could make this more clear.

Our test program also uses poll (We don't use select().)

BTW, is the above your saying related to your patch "[PATCH] pch_gpio: transform mutex into spinlock" ?
