mmc: sdhci-tegra: add basic support for Tegra114 (5ebf2552) · Commits · 戴 / test

The mmc controller on Tegra114 platforms is basically compatible with the settings used for Tegra30. However there is a difference where we don't need the extra ENABLE_SDHCI_SPEC_300 quirk as Tegra114 hardware advertises v3.0 support already. Signed-off-by:
