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