This fixes a very annoying regression on the Snowball SD card that has been around for a while. It turns out that the device tree does not configure the direction pins properly, nor sets up the pins for the voltage converter properly at boot. Unless all things are correctly set up, the feedback clock will not work, and makes the driver spew messages in the console (but it works, very slowly): root@Ux500:/ mount /dev/mmcblk0p2 /mnt/ [ 9.953460] mmci-pl18x 80126000.sdi0_per1: error during DMA transfer! [ 9.960296] mmcblk0: error -110 sending status command, retrying [ 9.966461] mmcblk0: error -110 sending status command, retrying [ 9.972534] mmcblk0: error -110 sending status command, aborting Fix this by rectifying the device tree to correspond to that of the Ux500 HREF boards plus the DAT31DIR setting that is unique for the Snowball, and things start working smoothly. Add in the SDR12 and SDR25 modes which this host can do without any problems. I don't know if this has ever been correct, sadly. It works after this patch.
