text: * Broadcom BCM7xxx Ethernet Systemport Controller (SYSTEMPORT)
  
  Required properties:
  - compatible: should be one of:
  	      "brcm,systemport-v1.00"
  	      "brcm,systemportlite-v1.00" or
  	      "brcm,systemport"
  - reg: address and length of the register set for the device.
  - interrupts: interrupts for the device, first cell must be for the rx
    interrupts, and the second cell should be for the transmit queues. An
    optional third interrupt cell for Wake-on-LAN can be specified
  - local-mac-address: Ethernet MAC address (48 bits) of this adapter
  - phy-mode: Should be a string describing the PHY interface to the
    Ethernet switch/PHY, see Documentation/devicetree/bindings/net/ethernet.txt
  - fixed-link: see Documentation/devicetree/bindings/net/fixed-link.txt for
    the property specific details
  
  Optional properties:
  - systemport,num-tier2-arb: number of tier 2 arbiters, an integer
  - systemport,num-tier1-arb: number of tier 1 arbiters, an integer
  - systemport,num-txq: number of HW transmit queues, an integer
  - systemport,num-rxq: number of HW receive queues, an integer
  
  Example:
  ethernet@f04a0000 {
  	compatible = "brcm,systemport-v1.00";
  	reg = <0xf04a0000 0x4650>;
  	local-mac-address = [ 00 11 22 33 44 55 ];
  	fixed-link = <0 1 1000 0 0>;
  	phy-mode = "gmii";
  	interrupts = <0x0 0x16 0x0>,
  		<0x0 0x17 0x0>;
  };
