This series contains the change for selection of bus speed mode. Previous implementation is complicated and some sequence is duplicated. And specially, HS400 mode eMMC5.0 is introduced this time. This patch-set has been tested in Exynos SoC. Note: This patch-set depends on "[PATCH RESEND v3 1/7] mmc: clarify DDR timing mode between SD-UHS and eMMC". Changes in v6: (6/6) Included "mmc: core: add DT bindings for eMMC HS400 1.8/1.2V" into this patch-set (5/6) Changed return type of prepare_hs400_tuning callback(int -> void) Changes in v5: (5/5) Added callback operation for HS400 target operation frequency instead of specific timing identifier. (2/5) Removed using union declaration. Changes in v4: (5/5)Reverting to HS mode is included in mmc_select_hs400() using __mmc_switch(). Changes in v3: Removed the function to check DDR type(mmc_snoop_ddr). Rebased with the latest branch. Seungwon Jeon (6): mmc: drop the speed mode of card's state mmc: identify available device type to select mmc: step power class after final selection of bus mode mmc: rework selection of bus speed mode mmc: add support for HS400 mode of eMMC5.0 mmc: add DT bindings for eMMC HS400 1.8/1.2V Documentation/devicetree/bindings/mmc/mmc.txt | 2 + drivers/mmc/core/bus.c | 9 +- drivers/mmc/core/core.c | 3 +- drivers/mmc/core/debugfs.c | 5 +- drivers/mmc/core/host.c | 4 + drivers/mmc/core/mmc.c | 666 +++++++++++++++---------- drivers/mmc/core/sd.c | 16 +- drivers/mmc/core/sd.h | 1 - drivers/mmc/core/sdio.c | 8 +- include/linux/mmc/card.h | 27 +- include/linux/mmc/host.h | 43 ++- include/linux/mmc/mmc.h | 23 +- 12 files changed, 486 insertions(+), 321 deletions(-) Thanks, sw-j -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
