| 2 | |
| 3 | Properties: |
| 4 | |
| 5 | - compatible : Should be "fsl,tsec" |
| 6 | - reg : Offset and length of the register set for the device |
| 7 | - phy-handle : See ethernet.txt file in the same directory. |
| 8 | - phy-connection-type : See ethernet.txt file in the same directory. This |
| 9 | property is only really needed if the connection is of type "rgmii-id", |
| 10 | "rgmii-rxid" and "rgmii-txid" as all other connection types are detected |
| 11 | by hardware. |
| 12 | |
| 13 | Example: |
| 14 | ethernet@24000 { |
| 15 | compatible = "fsl,tsec"; |
| 16 | reg = <0x24000 0x1000>; |
| 17 | phy-handle = <&phy0>; |
| 18 | phy-connection-type = "sgmii"; |
| 19 | }; |
| 20 | |
| 21 | Child nodes of the TSEC controller are typically the individual PHY devices |
| 22 | connected via the MDIO bus (sometimes the MDIO bus controller is separate). |
| 23 | |
| 24 | * MDIO IO device |
| 25 | |
| 26 | The MDIO is a bus to which the PHY devices are connected. For each |
| 27 | device that exists on this bus, a PHY node should be created. |
| 28 | |
| 29 | Required properties: |
| 30 | - compatible : Should define the compatible device type for the |
| 31 | mdio. Currently supported string/device is "fsl,tsec-mdio". |
| 32 | - reg : Offset and length of the register set for the device |
| 33 | |
| 34 | Example: |
| 35 | |
| 36 | mdio@24520 { |
| 37 | compatible = "fsl,tsec-mdio"; |
| 38 | reg = <0x24520 0x20>; |
| 39 | |
| 40 | ethernet-phy@0 { |
| 41 | reg = <0>; |
| 42 | }; |
| 43 | }; |
