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  transmit 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 transmit 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.
