Subject: [PATCH 5.8 12/17] arm64: tegra: Add missing timeout clock to Tegra186 SDMMC nodes
Date: Fri, 4 Sep 2020 15:30:11 +0200 [thread overview]
Message-ID: <20200904120258.593742953@linuxfoundation.org> (raw)
In-Reply-To: <20200904120257.983551609@linuxfoundation.org>
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")
