I am working on omap5912 and I am using linux 2.6.17. I am using a gpio to handle interrupts. I believe that I am having a noise interrupt which my firmware thinks is a really interrupt. Is there a way to distinguish a noise interrupt from a real interrupt?

It looks like you have a floating input. On omap2 it's possible to enable a pull-down on the pad. This is done using System Control Module (see TRM).
There may be an equivalent on omap5912.
