    Subject[PATCH] ARM: s3c64xx: mini6410: Correct card detect type for HSMMC1
    Date
    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.
