1 APM X-Gene SoC Ethernet nodes
3 Ethernet nodes are defined to describe on-chip ethernet interfaces in
6 Required properties for all the ethernet interfaces:
7 - compatible: Should state binding information from the following list,
8 - "apm,xgene-enet": RGMII based 1G interface
9 - "apm,xgene1-sgenet": SGMII based 1G interface
10 - "apm,xgene1-xgenet": XFI based 10G interface
11 - reg: Address and length of the register set for the device. It contains the
12 information of registers in the same order as described by reg-names
13 - reg-names: Should contain the register set names
14 - "enet_csr": Ethernet control and status register address space
15 - "ring_csr": Descriptor ring control and status register address space
16 - "ring_cmd": Descriptor ring command register address space
17 - interrupts: Ethernet main interrupt
18 - port-id: Port number (0 or 1)
19 - clocks: Reference to the clock entry.
20 - local-mac-address: MAC address assigned to this device
21 - phy-connection-type: Interface type between ethernet device and PHY device
23 Required properties for ethernet interfaces that have external PHY:
24 - phy-handle: Reference to a PHY node connected to this device
26 - mdio: Device tree subnode with the following required properties:
27 - compatible: Must be "apm,xgene-mdio".
28 - #address-cells: Must be <1>.
29 - #size-cells: Must be <0>.
31 For the phy on the mdio bus, there must be a node with the following fields:
32 - compatible: PHY identifier. Please refer ./phy.txt for the format.
33 - reg: The ID number for the phy.
36 - status: Should be "ok" or "disabled" for enabled/disabled. Default is "ok".
