+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.
