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.
