Tegra210 and later SDMMC hardware default uses sdmmc_legacy_tm (TMCLK) all the time for hardware data timeout instead of SDCLK and this TMCLK need to be kept enabled by Tegra sdmmc driver. This series includes patches to fix this for Tegra210/Tegra186/Tegra194. These patches need to be manually backported for 4.9, 4.14, 4.19, 5.4 Will send patches to backport separately once these patches are ack'd.
