| * Samsung 10G Ethernet driver (SXGBE) |
| |
| Required properties: |
| - compatible: Should be "samsung,sxgbe-v2.0a" |
| - reg: Address and length of the register set for the device |
| - interrupt-parent: Should be the phandle for the interrupt controller |
| that services interrupts for this device |
| - interrupts: Should contain the SXGBE interrupts |
| These interrupts are ordered by fixed and follows variable |
| trasmit DMA interrupts, receive DMA interrupts and lpi interrupt. |
| index 0 - this is fixed common interrupt of SXGBE and it is always |
| available. |
| index 1 to 25 - 8 variable trasmit interrupts, variable 16 receive interrupts |
| and 1 optional lpi interrupt. |
| - phy-mode: String, operation mode of the PHY interface. |
| Supported values are: "sgmii", "xgmii". |
| - samsung,pbl: Integer, Programmable Burst Length. |
| Supported values are 1, 2, 4, 8, 16, or 32. |
| - samsung,burst-map: Integer, Program the possible bursts supported by sxgbe |
| This is an interger and represents allowable DMA bursts when fixed burst. |
| Allowable range is 0x01-0x3F. When this field is set fixed burst is enabled. |
| When fixed length is needed for burst mode, it can be set within allowable |
| range. |
| |
| Optional properties: |
| - mac-address: 6 bytes, mac address |
| - max-frame-size: Maximum Transfer Unit (IEEE defined MTU), rather |
| than the maximum frame size. |
| |
| Example: |
| |
| aliases { |
| ethernet0 = <&sxgbe0>; |
| }; |
| |
| sxgbe0: ethernet@1a040000 { |
| compatible = "samsung,sxgbe-v2.0a"; |
| reg = <0 0x1a040000 0 0x10000>; |
| interrupt-parent = <&gic>; |
| interrupts = <0 209 4>, <0 185 4>, <0 186 4>, <0 187 4>, |
| <0 188 4>, <0 189 4>, <0 190 4>, <0 191 4>, |
| <0 192 4>, <0 193 4>, <0 194 4>, <0 195 4>, |
| <0 196 4>, <0 197 4>, <0 198 4>, <0 199 4>, |
| <0 200 4>, <0 201 4>, <0 202 4>, <0 203 4>, |
| <0 204 4>, <0 205 4>, <0 206 4>, <0 207 4>, |
| <0 208 4>, <0 210 4>; |
| samsung,pbl = <0x08> |
| samsung,burst-map = <0x20> |
| mac-address = [ 00 11 22 33 44 55 ]; /* Filled in by U-Boot */ |
| max-frame-size = <9000>; |
| phy-mode = "xgmii"; |
| }; |
