Your host driver has to 11 support handling this in order for it to be of any use. 12 13 If unsure, say N. 14 15config MMC_EMBEDDED_SDIO 16 boolean "MMC embedded SDIO device support (EXPERIMENTAL)" 17 help 18 If you say Y here, support will be added for embedded SDIO 19 devices which do not contain the necessary enumeration 20 support in hardware to be properly detected. 21 22config MMC_PARANOID_SD_INIT 23 bool "Enable paranoid SD card initialization (EXPERIMENTAL)" 24 help 25 If you say Y here, the MMC layer will be extra paranoid 26 about re-trying SD init requests. This can be a useful 27 work-around for buggy controllers and hardware. Enable 28 if you are experiencing issues with SD detection. 29
