I'm not familiar with this SoC, but a couple of quick searches on google
led me to the USB controller's reference guide. It looks like MUSB with
CPPI DMA, similar to what is in other Davinci chips. If so, there's a kernel
driver for it in Linux (see drivers/usb/musb/) with support for the DMA
engine as well.

OMAP3 uses MUSB with its own "Inventra" DMA engine.
