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