Tom Rini53633a82024-02-29 12:33:36 -05001* 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 "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
17Optional 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
25Optional 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.
