+Subject: dt-bindings: mmc: tegra: Add tmclk for Tegra210 and later
+
+From: Sowjanya Komatineni <skomatineni@nvidia.com>
+
+commit f7f86e8ac0ad7cd6792a80137f5a550924966916 upstream.
+
+commit b5a84ecf025a ("mmc: tegra: Add Tegra210 support")
+
+Tegra210 and later uses separate SDMMC_LEGACY_TM clock for data
+timeout.
+
+So, this patch adds "tmclk" to Tegra sdhci clock property in the
+device tree binding.
+
+Fixes: b5a84ecf025a ("mmc: tegra: Add Tegra210 support")
