+title: Socionext UniPhier USB2 PHY
+
+description: |
+ This describes the devicetree bindings for PHY interface built into
+ USB2 controller implemented on Socionext UniPhier SoCs.
+ Pro4 SoC has both USB2 and USB3 host controllers, however, this USB3
+ controller doesn't include its own High-Speed PHY. This needs to specify
+ USB2 PHY instead of USB3 HS-PHY.
