[PATCH v2] dt-bindings: usb: qcom,snps-dwc3: Add IPQ9650 compatible

From: Varadarajan Narayanan

Date: Thu Sep 24 2026 - 03:49:22 EST


Add the qcom,ipq9650-dwc3 compatible for the two DWC3 USB controllers found
on IPQ9650, using qcom,snps-dwc3 as the fallback compatible.

One controller is connected to a High-Speed PHY, while the other is
connected to both High-Speed and SuperSpeed PHYs.
