Hi,

I am writing a GPIO driver for a amd64 platform.  I see an option INTRNG
for GPIO interrupt handling in arm platforms.

Can we use INTRNG in amd64 platform? I tried compiling freebsd with
"options INTRNG" in amd64 platform, but it says "Unknown option INTRNG".
So, Just wanted to clarify whether INTRNG is supported in amd64? If not, is
there any equivalent available for amd64?

Also, Is there any available document which explains about INTRNG features?
