title: Qualcomm QMP USB3 DP PHY controller (SC7180)
description:
The QMP PHY controller supports physical layer functionality for a number of
controllers on Qualcomm chipsets, such as, PCIe, UFS and USB.
Note that these bindings are for SoCs up to SC8180X. For newer SoCs, see
qcom,sc8280xp-qmp-usb43dp-phy.yaml.
