-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, as well as the address
- and length of the AXI DMA controller IO space, unless
- axistream-connected is specified, in which case the reg
- attribute of the node referenced by it is used.
-- interrupts : Should be a list of 2 or 3 interrupts: TX DMA, RX DMA,
- and optionally Ethernet core. If axistream-connected is
- specified, the TX/RX DMA interrupts should be on that node
- instead, and only the Ethernet core interrupt is optionally
- specified here.
-- phy-handle : Should point to the external phy device if exists. Pointing
- this to the PCS/PMA PHY is deprecated and should be avoided.
- 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
-- xlnx,switch-x-sgmii : Boolean to indicate the Ethernet core is configured to
- support both 1000BaseX and SGMII modes. If set, the phy-mode
- should be set to match the mode selected on core reset (i.e.
- by the basex_or_sgmii core input line).
-- clock-names: Tuple listing input clock names. Possible clocks:
- s_axi_lite_clk: Clock for AXI register slave interface
- axis_clk: AXI4-Stream clock for TXD RXD TXC and RXS interfaces
- ref_clk: Ethernet reference clock, used by signal delay
- primitives and transceivers
- mgt_clk: MGT reference clock (used by optional internal
- PCS/PMA PHY)
-
- Note that if s_axi_lite_clk is not specified by name, the
- first clock of any name is used for this. If that is also not
- specified, the clock rate is auto-detected from the CPU clock
- (but only on platforms where this is possible). New device
- trees should specify all applicable clocks by name - the
- fallbacks to an unnamed clock or to CPU clock are only for
- backward compatibility.
-- clocks: Phandles to input clocks matching clock-names. Refer to common
- clock bindings.
-- axistream-connected: Reference to another node which contains the resources
- for the AXI DMA controller used by this device.
- If this is specified, the DMA-related resources from that
- device (DMA registers and DMA TX/RX interrupts) rather
- than this one will be used.
- - mdio : Child node for MDIO bus. Must be defined if PHY access is
- required through the core's MDIO interface (i.e. always,
- unless the PHY is accessed through a different bus).
- Non-standard MDIO bus frequency is supported via
- "clock-frequency", see mdio.yaml.
-
- - pcs-handle: Phandle to the internal PCS/PMA PHY in SGMII or 1000Base-X
- modes, where "pcs-handle" should be used to point
- to the PCS/PMA PHY, and "phy-handle" should point to an
- external PHY if exists.
-
-Example:
- axi_ethernet_eth: ethernet@40c00000 {
- compatible = "xlnx,axi-ethernet-1.00.a";
- device_type = "network";
- interrupt-parent = <µblaze_0_axi_intc>;
- interrupts = <2 0 1>;
- clock-names = "s_axi_lite_clk", "axis_clk", "ref_clk", "mgt_clk";
- clocks = <&axi_clk>, <&axi_clk>, <&pl_enet_ref_clk>, <&mgt_clk>;
- phy-mode = "mii";
- reg = <0x40c00000 0x40000 0x50c00000 0x40000>;
- xlnx,rxcsum = <0x2>;
- xlnx,rxmem = <0x800>;
