| * Marvell Armada 370 / Armada XP / Armada 3700 Ethernet Controller (NETA) |
| |
| Required properties: |
| - compatible: could be one of the following: |
| "marvell,armada-370-neta" |
| "marvell,armada-xp-neta" |
| "marvell,armada-3700-neta" |
| - reg: address and length of the register set for the device. |
| - interrupts: interrupt for the device |
| - phy: See ethernet.txt file in the same directory. |
| - phy-mode: See ethernet.txt file in the same directory |
| - clocks: List of clocks for this device. At least one clock is |
| mandatory for the core clock. If several clocks are given, then the |
| clock-names property must be used to identify them. |
| |
| Optional properties: |
| - tx-csum-limit: maximum mtu supported by port that allow TX checksum. |
| Value is presented in bytes. If not used, by default 1600B is set for |
| "marvell,armada-370-neta" and 9800B for others. |
| - clock-names: List of names corresponding to clocks property; shall be |
| "core" for core clock and "bus" for the optional bus clock. |
| |
| |
| Optional properties (valid only for Armada XP/38x): |
| |
| - buffer-manager: a phandle to a buffer manager node. Please refer to |
| Documentation/devicetree/bindings/net/marvell-neta-bm.txt |
| - bm,pool-long: ID of a pool, that will accept all packets of a size |
| higher than 'short' pool's threshold (if set) and up to MTU value. |
| Obligatory, when the port is supposed to use hardware |
| buffer management. |
| - bm,pool-short: ID of a pool, that will be used for accepting |
| packets of a size lower than given threshold. If not set, the port |
| will use a single 'long' pool for all packets, as defined above. |
| |
| Example: |
| |
| ethernet@70000 { |
| compatible = "marvell,armada-370-neta"; |
| reg = <0x70000 0x2500>; |
| interrupts = <8>; |
| clocks = <&gate_clk 4>; |
| tx-csum-limit = <9800> |
| phy = <&phy0>; |
| phy-mode = "rgmii-id"; |
| buffer-manager = <&bm>; |
| bm,pool-long = <0>; |
| bm,pool-short = <1>; |
| }; |
