I need to hold this on... May I ask you to explain your concern about this? I believe this bug fix is fine, since we still support board files for s3c64xx and DT based support is experimental at the moment. Best regards, Tomasz

According to board schematics, for HSMMC1 a GPIO line is used to detect card presence, while currently it is being configured for internal card detect line, which is multiplexed with card detect line of HSMMC0 and thus breaking it. This patch adds proper sdhci platform data setting card detect type to external GPIO and fixing operation of HSMMC0.
