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