* 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>;
|
|
};
