-* 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
-- clocks: When provided, must be two phandles to the functional clocks nodes of
-  the SYSTEMPORT block. The first phandle is the main SYSTEMPORT clock used
-  during normal operation, while the second phandle is the Wake-on-LAN clock.
-- clock-names: When provided, names of the functional clock phandles, first
-  name should be "sw_sysport" and second should be "sw_sysportwol".
-
-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>;
-};
