Subject: [PATCH v3 0/6] Fix timeout clock used by hardware data timeout

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:
[v3]:	Same as v2 with fixes tag

[v2]:	Includes minor fix
	- Patch-0006: parentheses around operand of '!'

Sowjanya Komatineni (6):
  sdhci: tegra: Remove SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK for Tegra210
  sdhci: tegra: Remove SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK for Tegra186
  arm64: tegra: Add missing timeout clock to Tegra210 SDMMC
  arm64: tegra: Add missing timeout clock to Tegra186 SDMMC nodes
  arm64: tegra: Add missing timeout clock to Tegra194 SDMMC nodes
  sdhci: tegra: Add missing TMCLK for data timeout
