Hisilicon hi3660 USB PHY
-----------------------
Required properties:
- compatible: should be "hisilicon,hi3660-usb-phy"
- #phy-cells: must be 0
- hisilicon,pericrg-syscon: phandle of syscon used to control phy.
- hisilicon,pctrl-syscon: phandle of syscon used to control phy.
- hisilicon,eye-diagram-param: parameter set for phy
Refer to phy/phy-bindings.txt for the generic PHY binding properties
This is a subnode of usb3_otg_bc register node.
Example:
usb3_otg_bc: usb3_otg_bc@ff200000 {
compatible = "syscon", "simple-mfd";
reg = <0x0 0xff200000 0x0 0x1000>;
usb-phy {
compatible = "hisilicon,hi3660-usb-phy";
#phy-cells = <0>;
hisilicon,pericrg-syscon = <&crg_ctrl>;
hisilicon,pctrl-syscon = <&pctrl>;
hisilicon,eye-diagram-param = <0x22466e4>;
};
};
