Subject: [PATCH v2 2/2] arm64: dts: qcom: x1e80100: Add USB Multiport
controller
From: Konrad Dybcio <konrad.dybcio@...aro.org>
X1E80100 has a multiport controller with 2 HS (eUSB) and 2 SS PHYs
attached to it. It's commonly used for USB-A ports and internally
routed devices. Configure it to support such functionality.
