The driver is based on the Linux driver and stripped down for barebox. This series is based on Rolf Evers Fischers work who unfortunately was not aware of Christoph Fritz work at that time. I used Rolfs driver to continue the work because his version already has device tree support. I decided to first add the necessary files of the MUSB driver without any changes and in a second patch add the barebox specific changes. This way we'll find the barebox changes in the repository. Instead of ifdeffing half of the driver away I removed the parts we don't need for barebox which keeps the driver in a readable state. Parts removed are: DMA, Host negotiation protocol and power management stuff. The driver has been tested in both host and device mode on the Beaglebone black and a custom board. On the Beaglebone the OTG port only works in device mode, I don't know why yet. The host port properly works in host mode though. The driver supports a poor mans otg mode. For device trees which specify dr_mode = "otg" the driver registers a otg device which has a 'mode' parameter which can be used to select host/peripheral mode during runtime. For example otg0.mode="host" specifies host mode. The same behaviour is implemented in the i.MX chipidea driver, the code for this should be merged at some point.
