| 2 | |
| 3 | Required 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 | |
| 18 | Optional 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 | |
| 24 | Examples (10G generic PHY): |
| 25 | nixge0: ethernet@40000000 { |
| 26 | compatible = "ni,xge-enet-3.00"; |
| 27 | reg = <0x40000000 0x4000 |
| 28 | 0x41002000 0x2000>; |

| 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 | |
| 49 | Examples (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 | |
| 65 | Examples (1G generic fixed-link + MDIO): |
| 66 | nixge0: ethernet@40000000 { |
| 67 | compatible = "ni,xge-enet-2.00"; |
| 68 | reg = <0x40000000 0x6000>; |
