No wp-gpios property means this is a µSD slot, right? Do you have any plans to enable sdr-50 and sdr-104? Is it not supported for some reason? I don't mind if its not enabled in this patch but I would like to know if it can be enabled or not and reflect that information in the wiki. http://elinux.org/index.php?title=Renesas-MMC-Enabled-Speeds
