* Marvell Armada 370 / Armada XP / Armada 3700 Ethernet Controller (NETA)
Required properties:
- compatible: could be one of the following:
- 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.
- phys: comphy for the ethernet port, see ../phy/phy-bindings.txt
Optional properties (valid only for Armada XP/38x):
- buffer-manager: a phandle to a buffer manager node. Please refer to
- 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.
