/**
* 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.
