* Faraday Technology FTGMAC100 gigabit ethernet controller |
|
|
|
Required properties: |
|
- compatible: "faraday,ftgmac100" |
|
|
|
Must also contain one of these if used as part of an Aspeed AST2400 |
|
or 2500 family SoC as they have some subtle tweaks to the |
|
implementation: |
|
|
|
- "aspeed,ast2400-mac" |
|
- "aspeed,ast2500-mac" |
|
- "aspeed,ast2600-mac" |
|
|
|
- reg: Address and length of the register set for the device |
|
- interrupts: Should contain ethernet controller interrupt |
|
|
|
Optional properties: |
|
- phy-handle: See ethernet.txt file in the same directory. |
|
- phy-mode: See ethernet.txt file in the same directory. If the property is |
|
absent, "rgmii" is assumed. Supported values are "rgmii*" and "rmii" for |
|
aspeed parts. Other (unknown) parts will accept any value. |
|
- use-ncsi: Use the NC-SI stack instead of an MDIO PHY. Currently assumes |
|
rmii (100bT) but kept as a separate property in case NC-SI grows support |
|
for a gigabit link. |
|
- no-hw-checksum: Used to disable HW checksum support. Here for backward |
|
compatibility as the driver now should have correct defaults based on |
|
the SoC. |
|
- clocks: In accordance with the generic clock bindings. Must describe the MAC |
|
IP clock, and optionally an RMII RCLK gate for the AST2500/AST2600. The |
|
required MAC clock must be the first cell. |
|
- clock-names: |
|
|
|
- "MACCLK": The MAC IP clock |
|
- "RCLK": Clock gate for the RMII RCLK |
|
|
|
Optional subnodes: |
|
- mdio: See mdio.txt file in the same directory. |
|
|
|
Example: |
|
|
|
mac0: ethernet@1e660000 { |
|
compatible = "aspeed,ast2500-mac", "faraday,ftgmac100"; |
|
reg = <0x1e660000 0x180>; |
|
interrupts = <2>; |
|
use-ncsi; |
|
}; |
|
|
|
Example with phy-handle: |
|
|
|
mac1: ethernet@1e680000 { |
|
compatible = "aspeed,ast2500-mac", "faraday,ftgmac100"; |
|
reg = <0x1e680000 0x180>; |
|
interrupts = <2>; |
|
|
|
phy-handle = <&phy>; |
|
phy-mode = "rgmii"; |
|
|
|
mdio { |
|
#address-cells = <1>; |
|
#size-cells = <0>; |
|
|
|
phy: ethernet-phy@1 { |
|
compatible = "ethernet-phy-ieee802.3-c22"; |
|
reg = <1>; |
|
}; |
|
}; |
|
};
