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