* Broadcom BCM7xxx Ethernet Systemport Controller (SYSTEMPORT)
2
+
3
+
Required properties:
4
+
- compatible: should be one of "brcm,systemport-v1.00" or "brcm,systemport"
5
+
- reg: address and length of the register set for the device.
6
+
- interrupts: interrupts for the device, first cell must be for the the rx
7
+
interrupts, and the second cell should be for the transmit queues
8
+
- local-mac-address: Ethernet MAC address (48 bits) of this adapter
9
+
- phy-mode: Should be a string describing the PHY interface to the
10
+
Ethernet switch/PHY, see Documentation/devicetree/bindings/net/ethernet.txt
11
+
- fixed-link: see Documentation/devicetree/bindings/net/fsl-tsec-phy.txt for
12
+
the property specific details
13
+
14
+
Optional properties:
15
+
- systemport,num-tier2-arb: number of tier 2 arbiters, an integer
16
+
- systemport,num-tier1-arb: number of tier 1 arbiters, an integer
17
+
- systemport,num-txq: number of HW transmit queues, an integer
18
+
- systemport,num-rxq: number of HW receive queues, an integer
