Subject: [PATCH 4.19 2/7] sdhci: tegra: Remove SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK for Tegra186
Date: Fri, 28 Aug 2020 15:25:12 -0700	[thread overview]
Message-ID: <1598653517-13658-3-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1598653517-13658-1-git-send-email-skomatineni@nvidia.com>

commit 4346b7c7941d ("mmc: tegra: Add Tegra186 support")

SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK is set for Tegra186 from the
beginning of its support in driver.

Tegra186 SDMMC hardware by default uses timeout clock (TMCLK) instead
of SDCLK and this quirk should not be set.

So, this patch remove this quirk for Tegra186.
