0248 * The Huawei device tree sets cd-gpios = <&msmgpio 38 GPIO_ACTIVE_HIGH>.

0250 * SD card, it's just low all the time. The Huawei kernel seems to use
0251 * polling for SD card detection instead.
0252 *
0253 * However, looking closer at the GPIO debug output it turns out that
0254 * gpio56 switches its state when inserting/removing the SD card.
0255 * It behaves just like gpio38 normally does. Usually GPIO56 is used as
0256 * "UIM2_PRESENT", i.e. to check if a second SIM card is inserted.
0257 * Maybe Huawei decided to replace the second SIM card slot with the
0258 * SD card slot and forgot to re-route to gpio38.
