Some uses chipidea internal UTMI PHY, in this case, only PHCD is needed to controller PHY's suspend/resume. Some does not use chipidea PHY (ULPI or vendor's UTMI PHY), in this case, PHY's operation is not only set/clear phcd, it may includes some others, like close PHY's analog part, PHY's clock, etc. So, I prefer to put PHY's operation at PHY's driver, it is platform related. -- Best Regards, Peter Chen -- 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
