Subject: [PATCH] HID: add ouya HID driver
This driver is a simple implementation to get the controller working and mapped properly.
This driver does not include functionality for the touchpad (yet). The original driver
was taken from from the ouya linux tree and has been simplified. It seems there may have
been other versions of the controller present that had a broken report descriptor. I have
removed that for now.
