It's been a while since I poked at this particular part of the code and board, is the gadget port one with a "normal" mini port, or do we need one of the USB A <-> USB A cables for it? My general recollection of when I did 6815a66ad7430 was that the device tree should control the ports in U-Boot itself.

I missed the logic of 6815a66ad7430. I understand now, so my patch was not suitable to fix the bug I encountered. Additional investigations revealed that usb0 'dr_mode' property is not overlayed to 'peripheral' in 'am335x-icev2-u-boot.dtsi'. That's why I saw this USB error. I'm going to fix that and send a new patch.

This patch fixes a bad condition for USB device definition. This prevents from getting a "No USB device found" error.
