I don't think there ever was a public one and I've never saw much any usable documentation for it anyways. The things to know if you need to fix something in the driver are: 1. The devctl register has different bits depending if musb is in peripheral or host mode. These are documented in the driver. 2. The hardware will try to do things on it's own to change it's state as an otg controller and there's no way to stop that. 3. In host mode, if the VBUS source does not come up fast enough musb will try to change state and won't stay in host mode. 4. The mainline Linux driver is missing dma handling for mode1 dma that would make mass storage faster. The old Nokia kernel tree has that implemented. Hope this helps a bit.
