To be more specific, I would think that the code change required in include/linux/mmc/card.h is:

#define mmc_card_mmc(c)         ((c)->type == MMC_TYPE_MMC)
- #define mmc_card_sd(c)          ((c)->type == MMC_TYPE_SD)
- #define mmc_card_sdio(c)        ((c)->type == MMC_TYPE_SDIO)

+ #define mmc_card_sd(c) ((c)->type == MMC_TYPE_SD || (c)->type == MMC_TYPE_SD_COMBO) + #define mmc_card_sdio(c) ((c)->type == MMC_TYPE_SDIO || (c)->type == MMC_TYPE_SD_COMBO)

Michal,

I hope you remember the email exchange we had about a month ago. I think I see an issue with SD-COMBO support.

In include/linux/mmc/card.h, there are macros:

#define mmc_card_mmc(c)         ((c)->type == MMC_TYPE_MMC)
#define mmc_card_sd(c)          ((c)->type == MMC_TYPE_SD)
#define mmc_card_sdio(c)        ((c)->type == MMC_TYPE_SDIO)

In particular, the mmc_card_sd(c) is invoked in many places, to determine whether the card is SD, and certain action is taken. Shouldn't the same be done for Combo cards, because these also have SD on them?

For instance, in drivers/mmc/core/core.c, routine mmc_set_data_timeout(), there is a call to mmc_card_sd(c).
Also, in drivers/mmc/card/block.c, routine mmc_blk_alloc().

I would appreciate your opinion on this.

Thanks,
Prashanth
