This patch fixes the wrong comparison before setting the interface voltage in DDR mode.
The assignment to the variable ddr before comaprison is either ddr = MMC_1_2V_DDR_MODE; or ddr == MMC_1_8V_DDR_MODE. But the comparison is done wth the extended csd value if (ddr == EXT_CSD_CARD_TYPE_DDR_1_2V) cc: Philip Rakity <prak...@marvell.com> cc: Arindam Nath <arindam.n...@amd.com> cc: Chris Ball <c...@laptop.org> Signed-off-by: Girish K S <girish.shivananja...@linaro.org> --- drivers/mmc/core/mmc.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/drivers/mmc/core/mmc.c b/drivers/mmc/core/mmc.c index 006e932..f0a9f1f 100644 --- a/drivers/mmc/core/mmc.c +++ b/drivers/mmc/core/mmc.c @@ -1058,7 +1058,7 @@ static int mmc_init_card(struct mmc_host *host, u32 ocr, * * WARNING: eMMC rules are NOT the same as SD DDR */ - if (ddr == EXT_CSD_CARD_TYPE_DDR_1_2V) { + if (ddr == MMC_1_2V_DDR_MODE) { err = mmc_set_signal_voltage(host, MMC_SIGNAL_VOLTAGE_120, 0); if (err) -- 1.7.1 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
