I'm not familiar with the s2c_hsotg.c driver, but if it can be made to support our hardware we're very interested in using it. I think dwc_otg is going to be a pain to mainline, and there are a number of issues with it so we're happy to move away from it. Assuming s2c_hsotg works as well or better than dwc_otg, we will switch to it. If Greg has R-Pi hardware and is able to help port s2c_hsotg to R-Pi that would be great. What is the license for s2c_hsotg? If it is dual licensed BSD+GPL then that's even better.
