275 * SD card, it's just low all the time. The Huawei kernel seems to use
276 * polling for SD card detection instead.
277 *
278 * However, looking closer at the GPIO debug output it turns out that
279 * gpio56 switches its state when inserting/removing the SD card.
280 * It behaves just like gpio38 normally does. Usually GPIO56 is used as
281 * "UIM2_PRESENT", i.e. to check if a second SIM card is inserted.
282 * Maybe Huawei decided to replace the second SIM card slot with the
283 * SD card slot and forgot to re-route to gpio38.
