Subject: [PATCH] arm64: dts: qcom: c630: Specify UFS device reset
Date: Sun, 5 Apr 2020 23:00:49 -0700 [thread overview]
Message-ID: <20200406060049.227029-1-bjorn.andersson@linaro.org> (raw)
On some device the reset line for the UFS memory needs to be tickled in
order for UFS to initialize properly, add this to the ufs_mem_hc node.
