Within this change, it seems reasonable to convert from using "ultra high speed" into "UHS-I speed", for the UHS-I type, as it should makes it more clear. Note that, the new print for UHS-II cards doesn't include the actual selected speed mode. Instead, this is going to be added from subsequent change. Signed-off-by: Ulf Hansson --- Updates in V14: - Move mmc_card_uhs2() to include/linux/mmc/host.h, so that mmc_card_uhs2() can be available for host drivers. Updates in V10: - Modify the commit message. Updates in V7: - Drop MMC_TIMING_SD_UHS2 in favor of MMC_TIMING_UHS2_SPEED_A in mmc_card_uhs2 function. Updates in V4: - Make mmc_card_uhs2() take struct mmc_host* as in-param. --- drivers/mmc/core/bus.c | 4 +++- include/linux/mmc/host.h | 8 ++++++++ 2 files changed, 11 insertions(+), 1 deletion(-) diff --git a/drivers/mmc/core/bus.c b/drivers/mmc/core/bus.c index 6731b46e855f..f9a67beb68f0 100644 --- a/drivers/mmc/core/bus.c +++ b/drivers/mmc/core/bus.c @@ -344,7 +344,9 @@ int mmc_add_card(struct mmc_card *card) if (mmc_card_hs(card)) speed_mode =3D "high speed "; else if (mmc_card_uhs(card)) - speed_mode =3D "ultra high speed "; + speed_mode =3D "UHS-I speed "; + else if (mmc_card_uhs2(card->host)) + speed_mode =3D "UHS-II speed "; else if (mmc_card_ddr52(card)) speed_mode =3D "high speed DDR "; else if (mmc_card_hs200(card)) diff --git a/include/linux/mmc/host.h b/include/linux/mmc/host.h index 21df3d6f7473..f1cf09ea1f72 100644 --- a/include/linux/mmc/host.h +++ b/include/linux/mmc/host.h @@ -637,6 +637,14 @@ static inline int mmc_card_uhs(struct mmc_card *card) card->host->ios.timing <=3D MMC_TIMING_UHS_DDR50; } =20 +static inline bool mmc_card_uhs2(struct mmc_host *host) +{ + return host->ios.timing =3D=3D MMC_TIMING_UHS2_SPEED_A || + host->ios.timing =3D=3D MMC_TIMING_UHS2_SPEED_A_HD || + host->ios.timing =3D=3D MMC_TIMING_UHS2_SPEED_B || + host->ios.timing =3D=3D MMC_TIMING_UHS2_SPEED_B_HD; +} + void mmc_retune_timer_stop(struct mmc_host *host); =20 static inline void mmc_retune_needed(struct mmc_host *host) --=20 2.25.1
