| 15 | * struct s3c_sdhci_platdata() - Platform device data for Samsung SDHCI | |
| 16 | * @max_width: The maximum number of data bits supported. | |
| 17 | * @host_caps: Standard MMC host capabilities bit field. | |
| 18 | * @host_caps2: The second standard MMC host capabilities bit field. | |
| 19 | * @cd_type: Type of Card Detection method (see cd_types enum above) | |
| 20 | * @ext_cd_init: Initialize external card detect subsystem. Called on | |
| 21 | * sdhci-s3c driver probe when cd_type == S3C_SDHCI_CD_EXTERNAL. | |
| 22 | * notify_func argument is a callback to the sdhci-s3c driver | |
| 23 | * that triggers the card detection event. Callback arguments: | |
| 24 | * dev is pointer to platform device of the host controller, | |
| 25 | * state is new state of the card (0 - removed, 1 - inserted). | |
| 26 | * @ext_cd_cleanup: Cleanup external card detect subsystem. Called on | |
| 27 | * sdhci-s3c driver remove when cd_type == S3C_SDHCI_CD_EXTERNAL. | |
| 28 | * notify_func argument is the same callback as for ext_cd_init. | |
| 29 | * @ext_cd_gpio: gpio pin used for external CD line, valid only if | |
| 30 | * cd_type == S3C_SDHCI_CD_GPIO | |
| 31 | * @ext_cd_gpio_invert: invert values for external CD gpio line | |
| 32 | * @cfg_gpio: Configure the GPIO for a specific card bit-width | |
| 33 | * | |
| 34 | * Initialisation data specific to either the machine or the platform | |
| 35 | * for the device driver to use or call-back when configuring gpio or | |
| 36 | * card speed information. | |
