This patch use card's tran_speed instead of hard setting value. I think mmc_set_clock(mmc, 52000000) is not good idea. because this is hard setting. we need use card's tran_speed.
So If card_caps did't support High speed, we need set card's speed value Signed-off-by: Jaehoon Chung <[email protected]> Signed-off-by: Minkyu Kang <[email protected]> Signed-off-by: Kyungmin Park <[email protected]> --- drivers/mmc/mmc.c | 9 +++++---- 1 files changed, 5 insertions(+), 4 deletions(-) diff --git a/drivers/mmc/mmc.c b/drivers/mmc/mmc.c index c543d83..f1b5552 100644 --- a/drivers/mmc/mmc.c +++ b/drivers/mmc/mmc.c @@ -815,11 +815,12 @@ int mmc_startup(struct mmc *mmc) if (mmc->card_caps & MMC_MODE_HS) { if (mmc->card_caps & MMC_MODE_HS_52MHz) - mmc_set_clock(mmc, 52000000); + mmc->tran_speed = 52000000; else - mmc_set_clock(mmc, 26000000); - } else - mmc_set_clock(mmc, 20000000); + mmc->tran_speed = 26000000; + } + + mmc_set_clock(mmc, mmc->tran_speed); } /* fill in device description */ _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
