Driver for Broadcom Northstar USB 3.0 PHY
|
|
|
|
Required properties:
|
|
|
|
- compatible: one of: "brcm,ns-ax-usb3-phy", "brcm,ns-bx-usb3-phy".
|
|
- reg: address of MDIO bus device
|
|
- usb3-dmp-syscon: phandle to syscon with DMP (Device Management Plugin)
|
|
registers
|
|
- #phy-cells: must be 0
|
|
|
|
Initialization of USB 3.0 PHY depends on Northstar version. There are currently
|
|
three known series: Ax, Bx and Cx.
|
|
Known A0: BCM4707 rev 0
|
|
Known B0: BCM4707 rev 4, BCM53573 rev 2
|
|
Known B1: BCM4707 rev 6
|
|
Known C0: BCM47094 rev 0
|
|
|
|
Example:
|
|
mdio: mdio@0 {
|
|
reg = <0x0>;
|
|
#size-cells = <1>;
|
|
#address-cells = <0>;
|
|
|
|
usb3-phy@10 {
|
|
compatible = "brcm,ns-ax-usb3-phy";
|
|
reg = <0x10>;
|
|
usb3-dmp-syscon = <&usb3_dmp>;
|
|
#phy-cells = <0>;
|
|
};
|
|
};
|
|
|
|
usb3_dmp: syscon@18105000 {
|
|
reg = <0x18105000 0x1000>;
|
|
};
