This is the same patch as what was applied to cubieboard2 https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/arch/arm/boot/dts/sun7i-a20-cubieboard2.dts?id=b8962f7ee700580a148e05eceb2302bcfc59ffbc which it looks like this hardware copies. I can power the Ibox using this USB socket and when I plug in a usb2ethernet device then it is detected.
