The Olinuxino has two USB sockets: USB0 is connected to a micro B socket. As it has the ID pin wired and the VBUS line connected to the PMIC, we describe it as a proper OTG socket, which switches between host and device automatically. USB1 is connected to a normal USB A socket. PG9 enables the power line, so add the required regulator as well.
