+* 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
+- 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 integer 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:
+- max-frame-size: Maximum Transfer Unit (IEEE defined MTU), rather
+ than the maximum frame size.
+
+The MAC address will be determined using the optional properties
+defined in ethernet.txt.
+
+Example:
+
+ aliases {
+ ethernet0 = <&sxgbe0>;
+ };
+
+ sxgbe0: ethernet@1a040000 {
+ compatible = "samsung,sxgbe-v2.0a";
+ reg = <0 0x1a040000 0 0x10000>;
+ interrupt-parent = <&gic>;
