* Broadcom BCM7xxx Ethernet Systemport Controller (SYSTEMPORT)

Required properties:
- compatible: should be one of "brcm,systemport-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>;
};
