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