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