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
13 * @detect_is_active_high: The state of the detect pin when it is active
14 * @non_removable: The slot is not removable, only detect once
16 * If a given slot is not present on the board, @bus_width should be
17 * set to 0. The other fields are ignored in this case.
19 * Any pins that aren't available should be set to a negative value.
21 * Note that support for multiple slots is experimental -- some cards
22 * might get upset if we don't get the clock management exactly right.
23 * But in most cases, it should work just fine.
