Subject: [PATCH v4 1/2] arm64: dts: qcom: sc7280: Add USB related nodes

Add nodes for DWC3 USB controller, QMP and HS USB PHYs in sc7280 SOC.

Signed-off-by: Sandeep Maheswaram <[email protected]>
Reviewed-by: Matthias Kaehlcke <[email protected]>
---
changed usb3-phy to lanes in qmp phy node as it was causing probe failure.

Is this another combo usb/dp phy?

This makes me think yes. In which case, can we put the final node in

phy@88e9200?

No, your sc7280 doesn't have a sm8250 UBS PHY.
