When CONFIG_DEBUG_FS is set, create a few files under /sys/kernel/debug containing information about an mmc host's internal state. Currently, just a single file is created, "ios", which contains information about the current operating parameters for the bus (clock speed, bus width, etc.) Host drivers can add additional files and directories under the host's root directory by passing the debugfs_root field in struct mmc_host as the 'parent' parameter to debugfs_create_*.
