Disable UHS modes until support for this is properly added. Signed-off-by: Lucas Stach Acked-by: Thierry Reding --- Ulf, this is a follow on patch to my Tegra UHS-I series. After reading the Tegra210 TRM I realized that the currently implemented tuning sequence will only work on Tegra30..Tegra124. If you don't keep your tree stable you might want to squash this into [PATCH v2 4/5] mmc: tegra: enable UHS-I modes, otherwise please pick this up as a fix on top. --- drivers/mmc/host/sdhci-tegra.c | 3 --- 1 file changed, 3 deletions(-) diff --git a/drivers/mmc/host/sdhci-tegra.c b/drivers/mmc/host/sdhci-tegra.c index b5abbe2..83c4bf7 100644 --- a/drivers/mmc/host/sdhci-tegra.c +++ b/drivers/mmc/host/sdhci-tegra.c @@ -353,9 +353,6 @@ static const struct sdhci_pltfm_data sdhci_tegra210_pdata = { static const struct sdhci_tegra_soc_data soc_data_tegra210 = { .pdata = &sdhci_tegra210_pdata, - .nvquirks = NVQUIRK_ENABLE_SDR50 | - NVQUIRK_ENABLE_DDR50 | - NVQUIRK_ENABLE_SDR104, }; static const struct of_device_id sdhci_tegra_dt_match[] = {
