Entry slot_name is used by userspace application to determinate if mmc block device is internal eMMC memory or external uSD card. So support for this property also in DT is needed. Here is simple patch which fix this problem: With this patch identification works fine: / # cat /sys/block/mmcblk0/device/../slot_name external / # cat /sys/block/mmcblk1/device/../slot_name internal Without patch omap_hsmmc driver does not create slot_name.
