7 * struct mci_slot_pdata - board-specific per-slot configuration
8 * @bus_width: Number of data lines wired up the slot
9 * @detect_pin: GPIO pin wired to the card detect switch
10 * @wp_pin: GPIO pin wired to the write protect sensor
11 * @detect_is_active_high: The state of the detect pin when it is active
13 * If a given slot is not present on the board, @bus_width should be
14 * set to 0. The other fields are ignored in this case.
16 * Any pins that aren't available should be set to a negative value.
18 * Note that support for multiple slots is experimental -- some cards
19 * might get upset if we don't get the clock management exactly right.
20 * But in most cases, it should work just fine.
