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>;
|
||
|
|
};
