Same remark as with your Olimex A20 EVB board patch, please also provide a vbus detect pin setting. If for some reason the VBus detect is not wired up, or not working properly, please mention this explicitly in the commit message.
Note that in some cases the axp209 is used for vbus detect, rather then a gpio, see e.g. :

Hans

Hi Hans,
I've added vbus detect and it no longer works. It's mentioned that the Itead Ibox is similar to the Cubieboard 2 which also doesn't include the detect. I can see now in the commit that it states "Note this board has the otg-vbus connected directly to the 5v-dcc of the board, so there is no vbus0 regulator, nor vbus0-det.", I will add this to the commit message and try and dig out a schematic to confirm. Thanks,
CK

Ok, thanks for looking into this.
