- * @cd_type: Type of Card Detection method (see cd_types enum above)
- * @ext_cd_init: Initialize external card detect subsystem. Called on

- * notify_func argument is a callback to the sdhci-s3c driver
- * that triggers the card detection event. Callback arguments:
- * dev is pointer to platform device of the host controller,
- * state is new state of the card (0 - removed, 1 - inserted).
- * @ext_cd_cleanup: Cleanup external card detect subsystem. Called on
- * sdhci-s3c driver remove when cd_type == S3C_SDHCI_CD_EXTERNAL.
- * notify_func argument is the same callback as for ext_cd_init.
- * @ext_cd_gpio: gpio pin used for external CD line, valid only if
- * cd_type == S3C_SDHCI_CD_GPIO
- * @ext_cd_gpio_invert: invert values for external CD gpio line
- * @cfg_gpio: Configure the GPIO for a specific card bit-width
- *
- * Initialisation data specific to either the machine or the platform
- * for the device driver to use or call-back when configuring gpio or
- * card speed information.
