[PATCH 1/3] arm64: dts: qcom: qdu1000: Add USB3 and PHY support

From: Komal Bajaj
Date: Tue Mar 19 2024 - 05:11:05 EST


Add devicetree nodes for enabling USB3 controller, Qcom QMP PHY and
SNPS HS PHY on QDU1000/QRU1000 SoCs. Also add required pins for USB,
so that the interface can work reliably.
