Interestingly enough, it looks like there's a reasonable chance that we won't be able to use the PHY port reset. We might have to go back to the full PHY reset (though it causes de-enumeration and re-enumeration) for safety, since there might be some side effects of the "phy port reset". Probably shouldn't land this series until we can figure that out. ...but in that case we still have the question of how we should export it. It would certainly be easy to keep using the reset framework... -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
