hi, all

         when i read the SarbreAI souce about SD card, i have a question for iomux setting of USDHC.

         for example, the SD_CD pin connects with GPIO_1 pad in SabreAI.

          According to chip manual , the pad should be set to ALT6

           but in source, it set the GPIO_1 pad to ALT5

           like this:

               //SD1_CD

              MX6Q_PAD_GPIO_1__GPIO_1_1,

 

         i don't know what the difference between them is.
