title: Socionext UniPhier USB3 Super-Speed (SS) 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 Super-Speed PHY.
