The eMMC 4.5 devices have support for 200MHz bus speed.The mmc core and host modules have been touched to add support for this module. It is necessary to know the card type in the sdhci.c file to add support for eMMC tuning function. So card.h file is included to import the card data structure. cc: Chris Ball Signed-off-by: Girish K S --- Changes in v5: Reduced the case statements for better code readability. Removed unused macro definitions. Modified the tuning function prototype and definition to support tuning for both SD and eMMC cards. Rebased to the latest chris-mmc branch. Changes in v4: Rebased onto chris-mmc/mmc-next branch. This patch is successfully applied on commit with id de022ed3fdc14808299b2fa66dbb1ed5ab921912. Changes in v3: In the previous commits of chris-mmc/mmc-next branch, the patch with commit id (c0f22a2c92e357e7cb3988b0b13034d70b7461f9) defines caps2 for more capabilities. This patch version deletes the member ext_caps(created in my earlier patch) from struct mmc_host and reuses already accepted caps2 member. Changes in v2: Rebased to latest chris-mmc/mmc-next branch. Resolved indentation problems identified in review. This patch has to be applied before the patch released for modifying the printk messages. Changes in v1: Case statements in switch that produce same result have been combined to reduce repeated assignments. patch recreated after rebase to chris balls mmc-next branch. drivers/mmc/core/bus.c | 3 +- drivers/mmc/core/mmc.c | 77 ++++++++++++++++++++++++++++++++++++++++---- drivers/mmc/core/sd.c | 3 +- drivers/mmc/core/sdio.c | 4 ++- drivers/mmc/host/sdhci.c | 38 +++++++++++++++++----- include/linux/mmc/card.h | 3 ++ include/linux/mmc/host.h | 11 ++++++- include/linux/mmc/mmc.h | 66 ++++++++++++++++++++++++++++++++++++++- include/linux/mmc/sdhci.h | 1 + 9 files changed, 185 insertions(+), 21 deletions(-) diff --git a/drivers/mmc/core/bus.c b/drivers/mmc/core/bus.c index 5639fdf..83c9f8d 100644 --- a/drivers/mmc/core/bus.c +++ b/drivers/mmc/core/bus.c @@ -301,10 +301,11 @@ int mmc_add_card(struct mmc_card *card) mmc_card_ddr_mode(card) ?
