-XILINX AXI ETHERNET Device Tree Bindings
---------------------------------------------------------
-
-Also called AXI 1G/2.5G Ethernet Subsystem, the xilinx axi ethernet IP core
-provides connectivity to an external ethernet PHY supporting different
-interfaces: MII, GMII, RGMII, SGMII, 1000BaseX. It also includes two
-segments of memory for buffering TX and RX, as well as the capability of
-offloading TX/RX checksum calculation off the processor.
-
-Management configuration is done through the AXI interface, while payload is
-sent and received through means of an AXI DMA controller. This driver
-includes the DMA driver code, so this driver is incompatible with AXI DMA
-driver.
-
-For more details about mdio please refer phy.txt file in the same directory.
-
-Required properties:
-- compatible : Must be one of "xlnx,axi-ethernet-1.00.a",
- "xlnx,axi-ethernet-1.01.a", "xlnx,axi-ethernet-2.01.a"
-- reg : Address and length of the IO space.
-- interrupts : Should be a list of two interrupt, TX and RX.
-- phy-handle : Should point to the external phy device.
- See ethernet.txt file in the same directory.
-- xlnx,rxmem : Set to allocated memory buffer for Rx/Tx in the hardware
-
-Optional properties:
-- phy-mode : See ethernet.txt
-- xlnx,phy-type : Deprecated, do not use, but still accepted in preference
- to phy-mode.
-- xlnx,txcsum : 0 or empty for disabling TX checksum offload,
- 1 to enable partial TX checksum offload,
- 2 to enable full TX checksum offload
-- xlnx,rxcsum : Same values as xlnx,txcsum but for RX checksum offload
-
-Example:
- axi_ethernet_eth: ethernet@40c00000 {
- compatible = "xlnx,axi-ethernet-1.00.a";
- device_type = "network";
- interrupt-parent = <&microblaze_0_axi_intc>;
- interrupts = <2 0>;
- phy-mode = "mii";
- reg = <0x40c00000 0x40000>;
- xlnx,rxcsum = <0x2>;
- xlnx,rxmem = <0x800>;
- xlnx,txcsum = <0x2>;
- phy-handle = <&phy0>;
- axi_ethernetlite_0_mdio: mdio {
- #address-cells = <1>;
- #size-cells = <0>;
- phy0: phy@0 {
- device_type = "ethernet-phy";
- reg = <1>;
- };
- };
- };
