| 1 | Broadcom USB3 phy binding for northstar plus SoC | ||
| 2 | The USB3 phy is internal to the SoC and is accessed using mdio interface. | ||
| 3 | |||
| 4 | Required mdio bus properties: | ||
| 5 | - reg: Should be 0x0 for SoC internal USB3 phy | ||
| 6 | - #address-cells: must be 1 | ||
| 7 | - #size-cells: must be 0 | ||
| 8 | |||
| 9 | Required USB3 PHY properties: | ||
| 10 | - compatible: should be "brcm,nsp-usb3-phy" | ||
| 11 | - reg: USB3 Phy address on SoC internal MDIO bus and it should be 0x10. | ||
| 12 | - usb3-ctrl-syscon: handler of syscon node defining physical address | ||
| 13 | of usb3 control register. | ||
| 14 | - #phy-cells: must be 0 | ||
| 15 | |||
| 16 | Required usb3 control properties: | ||
| 17 | - compatible: should be "brcm,nsp-usb3-ctrl" | ||
| 18 | - reg: offset and length of the control registers | ||
| 19 | |||
| 20 | Example: | ||
| 21 | |||
| 22 | mdio@0 { | ||
| 23 | reg = <0x0>; | ||
| 24 | #address-cells = <1>; | ||
| 25 | #size-cells = <0>; | ||
| 26 | |||
| 27 | usb3_phy: usb-phy@10 { | ||
| 28 | compatible = "brcm,nsp-usb3-phy"; | ||
| 29 | reg = <0x10>; | ||
| 30 | usb3-ctrl-syscon = <&usb3_ctrl>; | ||
| 31 | #phy-cells = <0>; | ||
| 32 | status = "disabled"; | ||
| 33 | }; | ||
| 34 | }; | ||
| 35 | |||
| 36 | usb3_ctrl: syscon@104408 { | ||
| 37 | compatible = "brcm,nsp-usb3-ctrl", "syscon"; | ||
| 38 | reg = <0x104408 0x3fc>; | ||
