1* Samsung 10G Ethernet driver (SXGBE) 2 3Required 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 trasmit 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 trasmit 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 23Optional properties: 24- max-frame-size: Maximum Transfer Unit (IEEE defined MTU), rather 25 than the maximum frame size. 26 27The MAC address will be determined using the optional properties 28defined in ethernet.txt. 29 30Example: 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 }; 53
