Hi Luiz,

Are those patches in the mainline kernel now? I couldn't find much info
on GPIO interrupts handling.

I'd like test/use them on AM335x (Beaglebone), but don't know what to
start with. How a useraland program can handle GPIO interrupts? I've
done that a lot in Linux, but need some directions/starting points for
FreeBSD.

Thanks,
Sergey
