The $11c register is specified to drive the lower capability register directly, hence you should use the sdhci defines for these bits instead of duplicating them here; SDHCI_CAN_DO_8BIT and SDHCI_CAN_VDD_300 that is. I'm sorry for missing this when looking at v1 :/ Regards, Bjorn -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
