162306a36Sopenharmony_ci* Samsung 10G Ethernet driver (SXGBE) 262306a36Sopenharmony_ci 362306a36Sopenharmony_ciRequired properties: 462306a36Sopenharmony_ci- compatible: Should be "samsung,sxgbe-v2.0a" 562306a36Sopenharmony_ci- reg: Address and length of the register set for the device 662306a36Sopenharmony_ci- interrupts: Should contain the SXGBE interrupts 762306a36Sopenharmony_ci These interrupts are ordered by fixed and follows variable 862306a36Sopenharmony_ci transmit DMA interrupts, receive DMA interrupts and lpi interrupt. 962306a36Sopenharmony_ci index 0 - this is fixed common interrupt of SXGBE and it is always 1062306a36Sopenharmony_ci available. 1162306a36Sopenharmony_ci index 1 to 25 - 8 variable transmit interrupts, variable 16 receive interrupts 1262306a36Sopenharmony_ci and 1 optional lpi interrupt. 1362306a36Sopenharmony_ci- phy-mode: String, operation mode of the PHY interface. 1462306a36Sopenharmony_ci Supported values are: "sgmii", "xgmii". 1562306a36Sopenharmony_ci- samsung,pbl: Integer, Programmable Burst Length. 1662306a36Sopenharmony_ci Supported values are 1, 2, 4, 8, 16, or 32. 1762306a36Sopenharmony_ci- samsung,burst-map: Integer, Program the possible bursts supported by sxgbe 1862306a36Sopenharmony_ci This is an integer and represents allowable DMA bursts when fixed burst. 1962306a36Sopenharmony_ci Allowable range is 0x01-0x3F. When this field is set fixed burst is enabled. 2062306a36Sopenharmony_ci When fixed length is needed for burst mode, it can be set within allowable 2162306a36Sopenharmony_ci range. 2262306a36Sopenharmony_ci 2362306a36Sopenharmony_ciOptional properties: 2462306a36Sopenharmony_ci- max-frame-size: Maximum Transfer Unit (IEEE defined MTU), rather 2562306a36Sopenharmony_ci than the maximum frame size. 2662306a36Sopenharmony_ci 2762306a36Sopenharmony_ciThe MAC address will be determined using the optional properties 2862306a36Sopenharmony_cidefined in ethernet.txt. 2962306a36Sopenharmony_ci 3062306a36Sopenharmony_ciExample: 3162306a36Sopenharmony_ci 3262306a36Sopenharmony_ci aliases { 3362306a36Sopenharmony_ci ethernet0 = <&sxgbe0>; 3462306a36Sopenharmony_ci }; 3562306a36Sopenharmony_ci 3662306a36Sopenharmony_ci sxgbe0: ethernet@1a040000 { 3762306a36Sopenharmony_ci compatible = "samsung,sxgbe-v2.0a"; 3862306a36Sopenharmony_ci reg = <0 0x1a040000 0 0x10000>; 3962306a36Sopenharmony_ci interrupt-parent = <&gic>; 4062306a36Sopenharmony_ci interrupts = <0 209 4>, <0 185 4>, <0 186 4>, <0 187 4>, 4162306a36Sopenharmony_ci <0 188 4>, <0 189 4>, <0 190 4>, <0 191 4>, 4262306a36Sopenharmony_ci <0 192 4>, <0 193 4>, <0 194 4>, <0 195 4>, 4362306a36Sopenharmony_ci <0 196 4>, <0 197 4>, <0 198 4>, <0 199 4>, 4462306a36Sopenharmony_ci <0 200 4>, <0 201 4>, <0 202 4>, <0 203 4>, 4562306a36Sopenharmony_ci <0 204 4>, <0 205 4>, <0 206 4>, <0 207 4>, 4662306a36Sopenharmony_ci <0 208 4>, <0 210 4>; 4762306a36Sopenharmony_ci samsung,pbl = <0x08> 4862306a36Sopenharmony_ci samsung,burst-map = <0x20> 4962306a36Sopenharmony_ci mac-address = [ 00 11 22 33 44 55 ]; /* Filled in by U-Boot */ 5062306a36Sopenharmony_ci max-frame-size = <9000>; 5162306a36Sopenharmony_ci phy-mode = "xgmii"; 5262306a36Sopenharmony_ci }; 53
