I don't think that this change should be made. >From what I understand from my discussions with Gumstix, early versions of the Overo COM used GPIO112 as indicated above. However all fab revisions >=2516 use GPIO0, so the code is correct for current and future versions of Overo COMs (as is the bootloader pinmuxing). In fact, future versions of Overo will use GPIO112 for a revision ID. Not an ideal situation, but I think we should leave things as they are since it matches current and future production. People with older boards will certainly need to use this patch to get vbus/id interrupts.
