    ARM: OMAP2: HSMMC: explicit fields to declare cover/card detect pin · b7a5646f
    Andreas Fenkart authored
    board-rx51 has no card detect pin in the mmc slot, but can detect that
    the (cell-phone) cover has been removed and the card is accessible.
    The semantics between cover/card detect differ, the gpio on the slot
    informs you after the card has been removed, cover removal does not
    necessarily mean that the card has been removed.
    This means different code paths are necessary. To complete this we
    also want different fields in the platform data for cover and card
    detect. This separation is not pushed all the way down into struct
    omap2_hsmmc_info which is used to initialize the platform data.
    If we did that we had to go over all board files and set the new
    gpio_cod pin to -EINVAL. If we forget one board or some out-of-tree
    archicture forgets that the default '0' is used which is a valid pin
    number.
