    1 * Marvell Armada 370 / Armada XP / Armada 3700 Ethernet Controller (NETA)
    2 
    3 Required 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 
   17 Optional 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 
   25 Optional 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 
   37 Example:
   38 
   39 ethernet@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 };
