title: Socionext UniPhier USB3 High-Speed (HS) PHY

description: |
  This describes the devicetree bindings for PHY interfaces built into
  USB3 controller implemented on Socionext UniPhier SoCs.
  Although the controller includes High-Speed PHY and Super-Speed PHY,
  this describes about High-Speed PHY.
