Odroid-xu3/4 didn't need to use the cd-gpios for detecting card. Because Host controller has the CDETECT register through SDx_CDN line. Host controller can know whether card is inserted or not with this register.
When i have checked the Odroid-xu3/4, they are using CDETECT register. (Not using exteranl cd-gpio.)
