| 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 | - interrupts: Should contain the SXGBE interrupts |
| 7 | These interrupts are ordered by fixed and follows variable |
| 8 | transmit DMA interrupts, receive DMA interrupts and lpi interrupt. |
| 9 | index 0 - this is fixed common interrupt of SXGBE and it is always |
| 10 | available. |
| 11 | index 1 to 25 - 8 variable transmit interrupts, variable 16 receive interrupts |
| 12 | and 1 optional lpi interrupt. |
| 13 | - phy-mode: String, operation mode of the PHY interface. |
| 14 | Supported values are: "sgmii", "xgmii". |
| 15 | - samsung,pbl: Integer, Programmable Burst Length. |
| 16 | Supported values are 1, 2, 4, 8, 16, or 32. |
| 17 | - samsung,burst-map: Integer, Program the possible bursts supported by sxgbe |
| 18 | This is an integer and represents allowable DMA bursts when fixed burst. |
| 19 | Allowable range is 0x01-0x3F. When this field is set fixed burst is enabled. |
| 20 | When fixed length is needed for burst mode, it can be set within allowable |
| 21 | range. |
| 22 | |
| 23 | Optional properties: |
| 24 | - max-frame-size: Maximum Transfer Unit (IEEE defined MTU), rather |
| 25 | than the maximum frame size. |
| 26 | |
| 27 | The MAC address will be determined using the optional properties |
| 28 | defined in ethernet.txt. |
| 29 | |
| 30 | Example: |
| 31 | |
| 32 | aliases { |
| 33 | ethernet0 = <&sxgbe0>; |
| 34 | }; |
| 35 | |
| 36 | sxgbe0: ethernet@1a040000 { |
| 37 | compatible = "samsung,sxgbe-v2.0a"; |
| 38 | reg = <0 0x1a040000 0 0x10000>; |
| 39 | interrupt-parent = <&gic>; |
| 40 | interrupts = <0 209 4>, <0 185 4>, <0 186 4>, <0 187 4>, |
| 41 | <0 188 4>, <0 189 4>, <0 190 4>, <0 191 4>, |
| 42 | <0 192 4>, <0 193 4>, <0 194 4>, <0 195 4>, |
| 43 | <0 196 4>, <0 197 4>, <0 198 4>, <0 199 4>, |
| 44 | <0 200 4>, <0 201 4>, <0 202 4>, <0 203 4>, |
| 45 | <0 204 4>, <0 205 4>, <0 206 4>, <0 207 4>, |
| 46 | <0 208 4>, <0 210 4>; |
| 47 | samsung,pbl = <0x08> |
| 48 | samsung,burst-map = <0x20> |
| 49 | mac-address = [ 00 11 22 33 44 55 ]; /* Filled in by U-Boot */ |
| 50 | max-frame-size = <9000>; |
| 51 | phy-mode = "xgmii"; |
| 52 | }; |
