     16 * struct s3c_sdhci_platdata() - Platform device data for Samsung SDHCI
     17 * @max_width: The maximum number of data bits supported.
     18 * @host_caps: Standard MMC host capabilities bit field.
     19 * @host_caps2: The second standard MMC host capabilities bit field.
     20 * @cd_type: Type of Card Detection method (see cd_types enum above)
     21 * @ext_cd_init: Initialize external card detect subsystem. Called on
     22 *		 sdhci-s3c driver probe when cd_type == S3C_SDHCI_CD_EXTERNAL.
     23 *		 notify_func argument is a callback to the sdhci-s3c driver
     24 *		 that triggers the card detection event. Callback arguments:
     25 *		 dev is pointer to platform device of the host controller,
     26 *		 state is new state of the card (0 - removed, 1 - inserted).
     27 * @ext_cd_cleanup: Cleanup external card detect subsystem. Called on
     28 *		 sdhci-s3c driver remove when cd_type == S3C_SDHCI_CD_EXTERNAL.
     29 *		 notify_func argument is the same callback as for ext_cd_init.
     30 * @ext_cd_gpio: gpio pin used for external CD line, valid only if
     31 *		 cd_type == S3C_SDHCI_CD_GPIO
     32 * @ext_cd_gpio_invert: invert values for external CD gpio line
     33 * @cfg_gpio: Configure the GPIO for a specific card bit-width
     34 *
     35 * Initialisation data specific to either the machine or the platform
     36 * for the device driver to use or call-back when configuring gpio or
     37 * card speed information.
