Later, Mr.Bin > suggested not to do this. Initially I thought the clearb/w() changes should be just a couple lines, so didn't think to separate it. But after reviewed the final implemenation, I agree Tony's comment is the right thing to do, please separate the musb core changes, each for clearb/w(), get/set_toggle(), and dma.
