1 | * Samsung 10G Ethernet driver (SXGBE) |
2 | ||
3 | Required properties: | |
4 | - compatible: Should be "samsung,sxgbe-v2.0a" | |
5 | - reg: Address and length of the register set for the device | |
6 | - interrupt-parent: Should be the phandle for the interrupt controller | |
7 | that services interrupts for this device | |
8 | - interrupts: Should contain the SXGBE interrupts | |
9 | These interrupts are ordered by fixed and follows variable | |
10 | trasmit DMA interrupts, receive DMA interrupts and lpi interrupt. | |
11 | index 0 - this is fixed common interrupt of SXGBE and it is always | |
12 | available. | |
13 | index 1 to 25 - 8 variable trasmit interrupts, variable 16 receive interrupts | |
14 | and 1 optional lpi interrupt. | |
15 | - phy-mode: String, operation mode of the PHY interface. | |
16 | Supported values are: "sgmii", "xgmii". | |
17 | - samsung,pbl: Integer, Programmable Burst Length. | |
18 | Supported values are 1, 2, 4, 8, 16, or 32. | |
19 | - samsung,burst-map: Integer, Program the possible bursts supported by sxgbe | |
20 | This is an interger and represents allowable DMA bursts when fixed burst. | |
21 | Allowable range is 0x01-0x3F. When this field is set fixed burst is enabled. | |
22 | When fixed length is needed for burst mode, it can be set within allowable | |
23 | range. | |
24 | ||
25 | Optional properties: | |
26 | - mac-address: 6 bytes, mac address | |
27 | - max-frame-size: Maximum Transfer Unit (IEEE defined MTU), rather | |
28 | than the maximum frame size. | |
29 | ||

32 | aliases { | |
33 | ethernet0 = <&sxgbe0>; | |
34 | }; | |
