1*c66ec88fSEmmanuel Vadot* Samsung 10G Ethernet driver (SXGBE) 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotRequired properties: 4*c66ec88fSEmmanuel Vadot- compatible: Should be "samsung,sxgbe-v2.0a" 5*c66ec88fSEmmanuel Vadot- reg: Address and length of the register set for the device 6*c66ec88fSEmmanuel Vadot- interrupts: Should contain the SXGBE interrupts 7*c66ec88fSEmmanuel Vadot These interrupts are ordered by fixed and follows variable 8*c66ec88fSEmmanuel Vadot trasmit DMA interrupts, receive DMA interrupts and lpi interrupt. 9*c66ec88fSEmmanuel Vadot index 0 - this is fixed common interrupt of SXGBE and it is always 10*c66ec88fSEmmanuel Vadot available. 11*c66ec88fSEmmanuel Vadot index 1 to 25 - 8 variable trasmit interrupts, variable 16 receive interrupts 12*c66ec88fSEmmanuel Vadot and 1 optional lpi interrupt. 13*c66ec88fSEmmanuel Vadot- phy-mode: String, operation mode of the PHY interface. 14*c66ec88fSEmmanuel Vadot Supported values are: "sgmii", "xgmii". 15*c66ec88fSEmmanuel Vadot- samsung,pbl: Integer, Programmable Burst Length. 16*c66ec88fSEmmanuel Vadot Supported values are 1, 2, 4, 8, 16, or 32. 17*c66ec88fSEmmanuel Vadot- samsung,burst-map: Integer, Program the possible bursts supported by sxgbe 18*c66ec88fSEmmanuel Vadot This is an integer and represents allowable DMA bursts when fixed burst. 19*c66ec88fSEmmanuel Vadot Allowable range is 0x01-0x3F. When this field is set fixed burst is enabled. 20*c66ec88fSEmmanuel Vadot When fixed length is needed for burst mode, it can be set within allowable 21*c66ec88fSEmmanuel Vadot range. 22*c66ec88fSEmmanuel Vadot 23*c66ec88fSEmmanuel VadotOptional properties: 24*c66ec88fSEmmanuel Vadot- max-frame-size: Maximum Transfer Unit (IEEE defined MTU), rather 25*c66ec88fSEmmanuel Vadot than the maximum frame size. 26*c66ec88fSEmmanuel Vadot 27*c66ec88fSEmmanuel VadotThe MAC address will be determined using the optional properties 28*c66ec88fSEmmanuel Vadotdefined in ethernet.txt. 29*c66ec88fSEmmanuel Vadot 30*c66ec88fSEmmanuel VadotExample: 31*c66ec88fSEmmanuel Vadot 32*c66ec88fSEmmanuel Vadot aliases { 33*c66ec88fSEmmanuel Vadot ethernet0 = <&sxgbe0>; 34*c66ec88fSEmmanuel Vadot }; 35*c66ec88fSEmmanuel Vadot 36*c66ec88fSEmmanuel Vadot sxgbe0: ethernet@1a040000 { 37*c66ec88fSEmmanuel Vadot compatible = "samsung,sxgbe-v2.0a"; 38*c66ec88fSEmmanuel Vadot reg = <0 0x1a040000 0 0x10000>; 39*c66ec88fSEmmanuel Vadot interrupt-parent = <&gic>; 40*c66ec88fSEmmanuel Vadot interrupts = <0 209 4>, <0 185 4>, <0 186 4>, <0 187 4>, 41*c66ec88fSEmmanuel Vadot <0 188 4>, <0 189 4>, <0 190 4>, <0 191 4>, 42*c66ec88fSEmmanuel Vadot <0 192 4>, <0 193 4>, <0 194 4>, <0 195 4>, 43*c66ec88fSEmmanuel Vadot <0 196 4>, <0 197 4>, <0 198 4>, <0 199 4>, 44*c66ec88fSEmmanuel Vadot <0 200 4>, <0 201 4>, <0 202 4>, <0 203 4>, 45*c66ec88fSEmmanuel Vadot <0 204 4>, <0 205 4>, <0 206 4>, <0 207 4>, 46*c66ec88fSEmmanuel Vadot <0 208 4>, <0 210 4>; 47*c66ec88fSEmmanuel Vadot samsung,pbl = <0x08> 48*c66ec88fSEmmanuel Vadot samsung,burst-map = <0x20> 49*c66ec88fSEmmanuel Vadot mac-address = [ 00 11 22 33 44 55 ]; /* Filled in by U-Boot */ 50*c66ec88fSEmmanuel Vadot max-frame-size = <9000>; 51*c66ec88fSEmmanuel Vadot phy-mode = "xgmii"; 52*c66ec88fSEmmanuel Vadot }; 53
