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