Intel Langwell and Penwell have almost the same implementation, so they can share the same code. For other hardware, I am not sure, but I had found some implementations accepted in kernel are different. For kernel OTG implementation, we did not have any spec like host side EHCI or something like peripheral side gadget framework to follow. So it seems quite hard to dig out a real common code for otg. So I hope more comments on those patches, then i will try to make it really useful to other otg stuffs.
