| 1 | | -The following properties are common to the Ethernet controllers: |
|---|
| 2 | | - |
|---|
| 3 | | -NOTE: All 'phy*' properties documented below are Ethernet specific. For the |
|---|
| 4 | | -generic PHY 'phys' property, see |
|---|
| 5 | | -Documentation/devicetree/bindings/phy/phy-bindings.txt. |
|---|
| 6 | | - |
|---|
| 7 | | -- local-mac-address: array of 6 bytes, specifies the MAC address that was |
|---|
| 8 | | - assigned to the network device; |
|---|
| 9 | | -- mac-address: array of 6 bytes, specifies the MAC address that was last used by |
|---|
| 10 | | - the boot program; should be used in cases where the MAC address assigned to |
|---|
| 11 | | - the device by the boot program is different from the "local-mac-address" |
|---|
| 12 | | - property; |
|---|
| 13 | | -- nvmem-cells: phandle, reference to an nvmem node for the MAC address; |
|---|
| 14 | | -- nvmem-cell-names: string, should be "mac-address" if nvmem is to be used; |
|---|
| 15 | | -- max-speed: number, specifies maximum speed in Mbit/s supported by the device; |
|---|
| 16 | | -- max-frame-size: number, maximum transfer unit (IEEE defined MTU), rather than |
|---|
| 17 | | - the maximum frame size (there's contradiction in the Devicetree |
|---|
| 18 | | - Specification). |
|---|
| 19 | | -- phy-mode: string, operation mode of the PHY interface. This is now a de-facto |
|---|
| 20 | | - standard property; supported values are: |
|---|
| 21 | | - * "internal" |
|---|
| 22 | | - * "mii" |
|---|
| 23 | | - * "gmii" |
|---|
| 24 | | - * "sgmii" |
|---|
| 25 | | - * "qsgmii" |
|---|
| 26 | | - * "tbi" |
|---|
| 27 | | - * "rev-mii" |
|---|
| 28 | | - * "rmii" |
|---|
| 29 | | - * "rgmii" (RX and TX delays are added by the MAC when required) |
|---|
| 30 | | - * "rgmii-id" (RGMII with internal RX and TX delays provided by the PHY, the |
|---|
| 31 | | - MAC should not add the RX or TX delays in this case) |
|---|
| 32 | | - * "rgmii-rxid" (RGMII with internal RX delay provided by the PHY, the MAC |
|---|
| 33 | | - should not add an RX delay in this case) |
|---|
| 34 | | - * "rgmii-txid" (RGMII with internal TX delay provided by the PHY, the MAC |
|---|
| 35 | | - should not add an TX delay in this case) |
|---|
| 36 | | - * "rtbi" |
|---|
| 37 | | - * "smii" |
|---|
| 38 | | - * "xgmii" |
|---|
| 39 | | - * "trgmii" |
|---|
| 40 | | - * "2000base-x", |
|---|
| 41 | | - * "2500base-x", |
|---|
| 42 | | - * "rxaui" |
|---|
| 43 | | - * "xaui" |
|---|
| 44 | | - * "10gbase-kr" (10GBASE-KR, XFI, SFI) |
|---|
| 45 | | -- phy-connection-type: the same as "phy-mode" property but described in the |
|---|
| 46 | | - Devicetree Specification; |
|---|
| 47 | | -- phy-handle: phandle, specifies a reference to a node representing a PHY |
|---|
| 48 | | - device; this property is described in the Devicetree Specification and so |
|---|
| 49 | | - preferred; |
|---|
| 50 | | -- phy: the same as "phy-handle" property, not recommended for new bindings. |
|---|
| 51 | | -- phy-device: the same as "phy-handle" property, not recommended for new |
|---|
| 52 | | - bindings. |
|---|
| 53 | | -- rx-fifo-depth: the size of the controller's receive fifo in bytes. This |
|---|
| 54 | | - is used for components that can have configurable receive fifo sizes, |
|---|
| 55 | | - and is useful for determining certain configuration settings such as |
|---|
| 56 | | - flow control thresholds. |
|---|
| 57 | | -- tx-fifo-depth: the size of the controller's transmit fifo in bytes. This |
|---|
| 58 | | - is used for components that can have configurable fifo sizes. |
|---|
| 59 | | -- managed: string, specifies the PHY management type. Supported values are: |
|---|
| 60 | | - "auto", "in-band-status". "auto" is the default, it usess MDIO for |
|---|
| 61 | | - management if fixed-link is not specified. |
|---|
| 62 | | - |
|---|
| 63 | | -Child nodes of the Ethernet controller are typically the individual PHY devices |
|---|
| 64 | | -connected via the MDIO bus (sometimes the MDIO bus controller is separate). |
|---|
| 65 | | -They are described in the phy.txt file in this same directory. |
|---|
| 66 | | -For non-MDIO PHY management see fixed-link.txt. |
