+ Tony

Hi Matt,

30 minutes too late for my pull request :-(

There are a couple of am33xx patches under discussion, so I'll take them
and send a for_3.7/dts-part2 pull request if this is not too late for Tony.

Or maybe you should just update the spec to use a 1-based GPIO number
like OMAP :-)

Regards,
Benoit
