1* NI XGE Ethernet controller 2 3Required properties: 4- compatible: Should be "ni,xge-enet-3.00", but can be "ni,xge-enet-2.00" for 5 older device trees with DMA engines co-located in the address map, 6 with the one reg entry to describe the whole device. 7- reg: Address and length of the register set for the device. It contains the 8 information of registers in the same order as described by reg-names. 9- reg-names: Should contain the reg names 10 "dma": DMA engine control and status region 11 "ctrl": MDIO and PHY control and status region 12- interrupts: Should contain tx and rx interrupt 13- interrupt-names: Should be "rx" and "tx" 14- phy-mode: See ethernet.txt file in the same directory. 15- nvmem-cells: Phandle of nvmem cell containing the MAC address 16- nvmem-cell-names: Should be "address" 17 18Optional properties: 19- mdio subnode to indicate presence of MDIO controller 20- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory. 21 Use instead of phy-handle. 22- phy-handle: See ethernet.txt file in the same directory. 23 24Examples (10G generic PHY): 25 nixge0: ethernet@40000000 { 26 compatible = "ni,xge-enet-3.00"; 27 reg = <0x40000000 0x4000 28 0x41002000 0x2000>; 29 reg-names = "dma", "ctrl"; 30 31 nvmem-cells = <ð1_addr>; 32 nvmem-cell-names = "address"; 33 34 interrupts = <0 29 IRQ_TYPE_LEVEL_HIGH>, <0 30 IRQ_TYPE_LEVEL_HIGH>; 35 interrupt-names = "rx", "tx"; 36 interrupt-parent = <&intc>; 37 38 phy-mode = "xgmii"; 39 phy-handle = <ðernet_phy1>; 40 41 mdio { 42 ethernet_phy1: ethernet-phy@4 { 43 compatible = "ethernet-phy-ieee802.3-c45"; 44 reg = <4>; 45 }; 46 }; 47 }; 48 49Examples (10G generic PHY, no MDIO): 50 nixge0: ethernet@40000000 { 51 compatible = "ni,xge-enet-2.00"; 52 reg = <0x40000000 0x6000>; 53 54 nvmem-cells = <ð1_addr>; 55 nvmem-cell-names = "address"; 56 57 interrupts = <0 29 IRQ_TYPE_LEVEL_HIGH>, <0 30 IRQ_TYPE_LEVEL_HIGH>; 58 interrupt-names = "rx", "tx"; 59 interrupt-parent = <&intc>; 60 61 phy-mode = "xgmii"; 62 phy-handle = <ðernet_phy1>; 63 }; 64 65Examples (1G generic fixed-link + MDIO): 66 nixge0: ethernet@40000000 { 67 compatible = "ni,xge-enet-2.00"; 68 reg = <0x40000000 0x6000>; 69 70 nvmem-cells = <ð1_addr>; 71 nvmem-cell-names = "address"; 72 73 interrupts = <0 29 IRQ_TYPE_LEVEL_HIGH>, <0 30 IRQ_TYPE_LEVEL_HIGH>; 74 interrupt-names = "rx", "tx"; 75 interrupt-parent = <&intc>; 76 77 phy-mode = "xgmii"; 78 79 fixed-link { 80 speed = <1000>; 81 pause; 82 link-gpios = <&gpio0 63 GPIO_ACTIVE_HIGH>; 83 }; 84 85 mdio { 86 ethernet_phy1: ethernet-phy@4 { 87 compatible = "ethernet-phy-ieee802.3-c22"; 88 reg = <4>; 89 }; 90 }; 91 92 };
