To move this to phy driver (just to avoid usage of a single flag) won't be a good idea. In this case, I'll also have to move some host controller specific flags to phy drv which won't be correct. > Li Jun -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
