+From: Bjorn Andersson <bjorn.andersson@linaro.org>
+
+The Lenovo Yoga C630 is built on the SDM850 from Qualcomm, but this seem
+to be similar enough to the SDM845 that we can reuse the sdm845.dtsi.
+
+Supported by this patch is: keyboard, battery monitoring, UFS storage,
+USB host and Bluetooth.

+ Yoga C630
+Date: Thu,  5 Sep 2019 20:24:12 +0100
+Message-Id: <20190905192412.23116-1-lee.jones@linaro.org>
+X-Mailer: git-send-email 2.17.1
+Sender: linux-arm-msm-owner@vger.kernel.org
+Precedence: bulk

+X-Mailing-List: linux-arm-msm@vger.kernel.org
+
+We have a production-level laptop (Lenovo Yoga C630) which is exhibiting
+a rather horrific bug.  When I2C HID devices are being scanned for at
+boot-time the QCom Geni based I2C (Serial Engine) attempts to use DMA.
+When it does, the laptop reboots and the user never sees the OS.
+
+Attempts are being made to debug the reason for the spontaneous reboot.
+No luck so far, hence the requirement for this hot-fix.  This workaround
+will be removed once we have a viable fix.

+When booting with ACPI, the Geni Serial Engine is not set as the I2C/SPI
+parent and thus, the wrapper (parent device) is unassigned.  This causes
+the kernel to crash with a null dereference error.
+
+Fixes: 8bc529b25354 ("soc: qcom: geni: Add support for ACPI")
