Subject: [PATCH v4 6/6] arm64: dts: qcom: c630: Add Embedded Controller
node
From: Bjorn Andersson <andersson@...nel.org>
The Embedded Controller in the Lenovo Yoga C630 is accessible on &i2c1
and provides battery and adapter status, as well as altmode
notifications for the second USB Type-C port.
Add a definition for the EC.
