Detailed Description

struct s3c24xx_mci_pdata - sd/mmc controller platform data : Set this to indicate there is no write-protect switch. : Set this if there is no detect switch. : Invert the default sense of the write protect switch. : Invert the default sense of the write protect switch. : Set to allow the use of DMA. : GPIO number for the card detect line. : GPIO number for the write protect line. : The mask of the available power states, non-zero to use. : Callback to control the power mode.

The is used for card detection when is unset, and the default sense is that 0 returned from gpio_get_value() means that a card is inserted. If is set, then the value from gpio_get_value() is inverted, which makes 1 mean card inserted.

The driver will use to signal whether the card is write protected if is not set. A 0 returned from gpio_get_value() means the card is read/write, and 1 means read-only. The will invert the value returned from gpio_get_value().

Card power is set by , using MCC_VDD_ constants if it is set to a non-zero value, otherwise the default of 3.2-3.4V is used.
