1* Marvell Armada 370 / Armada XP / Armada 3700 Ethernet Controller (NETA) 2 3Required properties: 4- compatible: could be one of the following: 5 "marvell,armada-370-neta" 6 "marvell,armada-xp-neta" 7 "marvell,armada-3700-neta" 8 "marvell,armada-ac5-neta" 9- reg: address and length of the register set for the device. 10- interrupts: interrupt for the device 11- phy: See ethernet.txt file in the same directory. 12- phy-mode: See ethernet.txt file in the same directory 13- clocks: List of clocks for this device. At least one clock is 14 mandatory for the core clock. If several clocks are given, then the 15 clock-names property must be used to identify them. 16 17Optional properties: 18- tx-csum-limit: maximum mtu supported by port that allow TX checksum. 19 Value is presented in bytes. If not used, by default 1600B is set for 20 "marvell,armada-370-neta" and 9800B for others. 21- clock-names: List of names corresponding to clocks property; shall be 22 "core" for core clock and "bus" for the optional bus clock. 23- phys: comphy for the ethernet port, see ../phy/phy-bindings.txt 24 25Optional properties (valid only for Armada XP/38x): 26 27- buffer-manager: a phandle to a buffer manager node. Please refer to 28 Documentation/devicetree/bindings/net/marvell-neta-bm.txt 29- bm,pool-long: ID of a pool, that will accept all packets of a size 30 higher than 'short' pool's threshold (if set) and up to MTU value. 31 Obligatory, when the port is supposed to use hardware 32 buffer management. 33- bm,pool-short: ID of a pool, that will be used for accepting 34 packets of a size lower than given threshold. If not set, the port 35 will use a single 'long' pool for all packets, as defined above. 36 37Example: 38 39ethernet@70000 { 40 compatible = "marvell,armada-370-neta"; 41 reg = <0x70000 0x2500>; 42 interrupts = <8>; 43 clocks = <&gate_clk 4>; 44 tx-csum-limit = <9800> 45 phy = <&phy0>; 46 phy-mode = "rgmii-id"; 47 buffer-manager = <&bm>; 48 bm,pool-long = <0>; 49 bm,pool-short = <1>; 50}; 51
