37 * struct s3c_sdhci_platdata() - Platform device data for Samsung SDHCI
38 * @max_width: The maximum number of data bits supported.
39 * @host_caps: Standard MMC host capabilities bit field.
40 * @host_caps2: The second standard MMC host capabilities bit field.
41 * @cd_type: Type of Card Detection method (see cd_types enum above)
42 * @ext_cd_init: Initialize external card detect subsystem. Called on
43 * sdhci-s3c driver probe when cd_type == S3C_SDHCI_CD_EXTERNAL.
44 * notify_func argument is a callback to the sdhci-s3c driver
45 * that triggers the card detection event. Callback arguments:
46 * dev is pointer to platform device of the host controller,
47 * state is new state of the card (0 - removed, 1 - inserted).
48 * @ext_cd_cleanup: Cleanup external card detect subsystem. Called on
49 * sdhci-s3c driver remove when cd_type == S3C_SDHCI_CD_EXTERNAL.
50 * notify_func argument is the same callback as for ext_cd_init.
51 * @ext_cd_gpio: gpio pin used for external CD line, valid only if
52 * cd_type == S3C_SDHCI_CD_GPIO
53 * @ext_cd_gpio_invert: invert values for external CD gpio line
54 * @cfg_gpio: Configure the GPIO for a specific card bit-width
55 *
56 * Initialisation data specific to either the machine or the platform
57 * for the device driver to use or call-back when configuring gpio or
58 * card speed information.
