Can you add:
dr_mode = "otg";
to the usb_otg node?
According to the generic binding doc this should be the default if not
specified, but the sunxi-musb driver requires this property, explicitly.
And on the way, can you drop the usb0_vbus-supply property from the
usbphy node, to see if that makes a difference? Maybe the polarity of
the pin is messed up?
Cheers,
Andre.
