Subject: [PATCH v2 4.19 0/7] Fix timeout clock used by hardware data timeout
Date: Tue, 1 Sep 2020 09:24:43 -0700 [thread overview]
Message-ID: <1598977490-1826-1-git-send-email-skomatineni@nvidia.com> (raw)
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 manual backport patches to fix this for stable
kernel #4.19
Note:
Patch series v2 is same as v1 except updated commit message in all patches
properly for backporting.
