Subject: [PATCH] arm64: dts: qcom: kitakami: Temporarily disable SDHCI1
Date: Fri, 14 Aug 2020 17:47:49 +0200 [thread overview]
Message-ID: <20200814154749.257837-1-konradybcio@gmail.com> (raw)
There is an issue with Kitakami eMMCs dying when a quirk
isn't addressed. Until that happens, disable it.
Signed-off-by: Konrad Dybcio <konradybcio@gmail.com>

This supersides my previous "mmc: host: msm: Add optional full power cycle property."
series in which I incorrectly addressed the issue NOT solving the cause.
