+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.

-Socionext UniPhier USB2 PHY
-
-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.
-
-Required properties:
-- compatible: Should contain one of the following:
-    "socionext,uniphier-pro4-usb2-phy" - for Pro4 SoC
-    "socionext,uniphier-ld11-usb2-phy" - for LD11 SoC
-
-Sub-nodes:
-Each PHY should be represented as a sub-node.
-
-Sub-nodes required properties:
-- #phy-cells: Should be 0.
-- reg: The number of the PHY.
-
-Sub-nodes optional properties:
-- vbus-supply: A phandle to the regulator for USB VBUS.
-
-Refer to phy/phy-bindings.txt for the generic PHY binding properties.
-
-Example:
-	soc-glue@5f800000 {
-		...
-		usb-phy {
-			compatible = "socionext,uniphier-ld11-usb2-phy";
-			usb_phy0: phy@0 {
-				reg = <0>;
-				#phy-cells = <0>;
-			};
-			...
-		};
-	};
-
-	usb@5a800100 {
-		compatible = "socionext,uniphier-ehci", "generic-ehci";
-		...
-		phy-names = "usb";
-		phys = <&usb_phy0>;
-	};
