+Subject: arm64: tegra: Add missing timeout clock to Tegra186 SDMMC nodes
+
+From: Sowjanya Komatineni <skomatineni@nvidia.com>
+
+commit baba217d2c4446b6eef309d81d8776cb5c68cb55 upstream.
+
+commit 39cb62cb8973 ("arm64: tegra: Add Tegra186 support")
+
+Tegra186 uses separate SDMMC_LEGACY_TM clock for data timeout and
+this clock is not enabled currently which is not recommended.
+
+Tegra186 SDMMC advertises 12Mhz as timeout clock frequency in host
+capability register and uses it by default.
+
+So, this clock should be kept enabled by the SDMMC driver.
+
+Fixes: 39cb62cb8973 ("arm64: tegra: Add Tegra186 support")
