-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>;
- };
