From: Axel Haslam <ahaslam@xxxxxxxxxxxx>
The omap138-lcdk and its predecessor the hawk board don't have gpios
connected to control vbus or get the over current notifications for usb.
for example, in the hawk board gpio6-13 is connected to a LED, and
gpio2-4 is not connected at all. In the lcdk board, gpio 2-4 is a push
button, and gpio6-13 is connected to a LED.
Remove the gpio and interrupt registration for these pins.
