^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) - interrupts: interrupt for the device
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) - phy: See ethernet.txt file in the same directory.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) - phy-mode: See ethernet.txt file in the same directory
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) - clocks: List of clocks for this device. At least one clock is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) mandatory for the core clock. If several clocks are given, then the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) clock-names property must be used to identify them.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) Optional properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) - tx-csum-limit: maximum mtu supported by port that allow TX checksum.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) Value is presented in bytes. If not used, by default 1600B is set for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) "marvell,armada-370-neta" and 9800B for others.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) - clock-names: List of names corresponding to clocks property; shall be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) "core" for core clock and "bus" for the optional bus clock.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) - phys: comphy for the ethernet port, see ../phy/phy-bindings.txt
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) Optional properties (valid only for Armada XP/38x):
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) - buffer-manager: a phandle to a buffer manager node. Please refer to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) Documentation/devicetree/bindings/net/marvell-neta-bm.txt
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) - bm,pool-long: ID of a pool, that will accept all packets of a size
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) higher than 'short' pool's threshold (if set) and up to MTU value.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) Obligatory, when the port is supposed to use hardware
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) buffer management.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) - bm,pool-short: ID of a pool, that will be used for accepting
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) packets of a size lower than given threshold. If not set, the port
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) will use a single 'long' pool for all packets, as defined above.
