Tegra210/Tegra186/Tegra194 has incorrectly enabled SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK from the beginning of their support.
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 and 4.19.
Will send patches to backport separately once these patches are ack'd.
Delta between patch versions: [v4]: Include additional dt-binding patch
[v3]: Same as v2 with fixes tag
[v2]: Includes minor fix - Patch-0006: parentheses around operand of '!'
