+/**
+ * struct s3c24xx_mci_pdata - sd/mmc controller platform data
+ * @no_wprotect: Set this to indicate there is no write-protect switch.
+ * @no_detect: Set this if there is no detect switch.
+ * @wprotect_invert: Invert the default sense of the write protect switch.
+ * @detect_invert: Invert the default sense of the write protect switch.
+ * @use_dma: Set to allow the use of DMA.
+ * @gpio_detect: GPIO number for the card detect line.
+ * @gpio_wprotect: GPIO number for the write protect line.
+ * @ocr_avail: The mask of the available power states, non-zero to use.
+ * @set_power: Callback to control the power mode.
+ *
+ * The @gpio_detect is used for card detection when @no_wprotect is unset,
+ * and the default sense is that 0 returned from gpio_get_value() means
+ * that a card is inserted. If @detect_invert is set, then the value from
+ * gpio_get_value() is inverted, which makes 1 mean card inserted.
+ *
+ * The driver will use @gpio_wprotect to signal whether the card is write
+ * protected if @no_wprotect is not set. A 0 returned from gpio_get_value()
+ * means the card is read/write, and 1 means read-only. The @wprotect_invert
+ * will invert the value returned from gpio_get_value().
+ *
+ * Card power is set by @ocr_availa, using MCC_VDD_ constants if it is set
+ * to a non-zero value, otherwise the default of 3.2-3.4V is used.
