Reference on GPIO programming with Intel PXA
In my quest to make the USB controller to work without messing the rest of the system, I've found an interesting reference about GPIO configuration for linux ARM. Devices may be activated/deactivated with GPIO ports and, as described in TE2 forum thread at hackndev, USB requires controling GPIO 53.
