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 for all the ethernet interfaces: 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 19Required properties for ethernet interfaces that have external PHY: 20- phy-handle: Reference to a PHY node connected to this device 21 22- mdio: Device tree subnode with the following required properties: 23 - compatible: Must be "apm,xgene-mdio". 24 - #address-cells: Must be <1>. 25 - #size-cells: Must be <0>. 26 27 For the phy on the mdio bus, there must be a node with the following fields: 28 - compatible: PHY identifier. Please refer ./phy.txt for the format. 29 - reg: The ID number for the phy. 30 31Optional properties: 32- status: Should be "ok" or "disabled" for enabled/disabled. Default is "ok". 33 34Example: 35 menetclk: menetclk { 36 compatible = "apm,xgene-device-clock"; 37 clock-output-names = "menetclk"; 38 status = "ok"; 39 }; 40 41 menet: ethernet@17020000 { 42 compatible = "apm,xgene-enet"; 43 status = "disabled"; 44 reg = <0x0 0x17020000 0x0 0xd100>, 45 <0x0 0X17030000 0x0 0X400>, 46 <0x0 0X10000000 0x0 0X200>; 47 reg-names = "enet_csr", "ring_csr", "ring_cmd"; 48 interrupts = <0x0 0x3c 0x4>; 49 clocks = <&menetclk 0>; 50 local-mac-address = [00 01 73 00 00 01]; 51 phy-connection-type = "rgmii"; 52 phy-handle = <&menetphy>; 53 mdio { 54 compatible = "apm,xgene-mdio"; 55 #address-cells = <1>; 56 #size-cells = <0>; 57 menetphy: menetphy@3 { 58 compatible = "ethernet-phy-id001c.c915"; 59 reg = <0x3>; 60 }; 61 62 }; 63 }; 64 65/* Board-specific peripheral configurations */ 66&menet { 67 status = "ok"; 68}; 69
