R8A66597 is a discrete USB host and peripheral controller chip that
supports both full and high speed USB 2.0 data transfers.
It has nine configurable endpoints, and endpoint zero.
Say "y" to link the driver statically, or "m" to build a
dynamically linked module called "r8a66597_udc" and force all
gadget drivers to also be dynamically linked.
