1APM X-Gene SoC Ethernet nodes
2
3Ethernet nodes are defined to describe on-chip ethernet interfaces in
4APM X-Gene SoC.
5
6Required properties:
7- compatible: Should be "apm,xgene-enet"
8- reg: Address and length of the register set for the device. It contains the
9  information of registers in the same order as described by reg-names
10- reg-names: Should contain the register set names
11  - "enet_csr": Ethernet control and status register address space
12  - "ring_csr": Descriptor ring control and status register address space
13  - "ring_cmd": Descriptor ring command register address space
14- interrupts: Ethernet main interrupt
15- clocks: Reference to the clock entry.
16- local-mac-address: MAC address assigned to this device
17- phy-connection-type: Interface type between ethernet device and PHY device
18- phy-handle: Reference to a PHY node connected to this device
19
20- mdio: Device tree subnode with the following required properties:
21  - compatible: Must be "apm,xgene-mdio".
22  - #address-cells: Must be <1>.
23  - #size-cells: Must be <0>.
24
25  For the phy on the mdio bus, there must be a node with the following fields:
26  - compatible: PHY identifier.  Please refer ./phy.txt for the format.
27  - reg: The ID number for the phy.
28
29Optional properties:
30- status: Should be "ok" or "disabled" for enabled/disabled. Default is "ok".

34		compatible = "apm,xgene-device-clock";
35		clock-output-names = "menetclk";
36		status = "ok";
37	};
38
39	menet: ethernet@17020000 {
40		compatible = "apm,xgene-enet";
41		status = "disabled";
42		reg = <0x0 0x17020000 0x0 0xd100>,
43		      <0x0 0X17030000 0x0 0X400>,
44		      <0x0 0X10000000 0x0 0X200>;
45		reg-names = "enet_csr", "ring_csr", "ring_cmd";
46		interrupts = <0x0 0x3c 0x4>;
47		clocks = <&menetclk 0>;
48		local-mac-address = [00 01 73 00 00 01];
49		phy-connection-type = "rgmii";
50		phy-handle = <&menetphy>;
51		mdio {
52			compatible = "apm,xgene-mdio";
53			#address-cells = <1>;
54			#size-cells = <0>;
55			menetphy: menetphy@3 {
56				compatible = "ethernet-phy-id001c.c915";
57				reg = <0x3>;
58			};
