+* 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>;
+};
