1* Marvell Armada 370 / Armada XP Ethernet Controller (NETA) 2 3Required properties: 4- compatible: "marvell,armada-370-neta" or "marvell,armada-xp-neta". 5- reg: address and length of the register set for the device. 6- interrupts: interrupt for the device 7- phy: See ethernet.txt file in the same directory. 8- phy-mode: See ethernet.txt file in the same directory 9- clocks: List of clocks for this device. At least one clock is 10 mandatory for the core clock. If several clocks are given, then the 11 clock-names property must be used to identify them. 12 13Optional properties: 14- tx-csum-limit: maximum mtu supported by port that allow TX checksum. 15 Value is presented in bytes. If not used, by default 1600B is set for 16 "marvell,armada-370-neta" and 9800B for others. 17- clock-names: List of names corresponding to clocks property; shall be 18 "core" for core clock and "bus" for the optional bus clock. 19 20 21Optional properties (valid only for Armada XP/38x): 22 23- buffer-manager: a phandle to a buffer manager node. Please refer to 24 Documentation/devicetree/bindings/net/marvell-neta-bm.txt 25- bm,pool-long: ID of a pool, that will accept all packets of a size 26 higher than 'short' pool's threshold (if set) and up to MTU value. 27 Obligatory, when the port is supposed to use hardware 28 buffer management. 29- bm,pool-short: ID of a pool, that will be used for accepting 30 packets of a size lower than given threshold. If not set, the port 31 will use a single 'long' pool for all packets, as defined above. 32 33Example: 34 35ethernet@70000 { 36 compatible = "marvell,armada-370-neta"; 37 reg = <0x70000 0x2500>; 38 interrupts = <8>; 39 clocks = <&gate_clk 4>; 40 tx-csum-limit = <9800> 41 status = "okay"; 42 phy = <&phy0>; 43 phy-mode = "rgmii-id"; 44 buffer-manager = <&bm>; 45 bm,pool-long = <0>; 46 bm,pool-short = <1>; 47}; 48
