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