* Calxeda Highbank 10Gb XGMAC Ethernet
Required properties:
- compatible : Should be "calxeda,hb-xgmac"
- reg : Address and length of the register set for the device
- interrupts : Should contain 3 xgmac interrupts. The 1st is main interrupt.
The 2nd is pwr mgt interrupt. The 3rd is low power state interrupt.
Optional properties:
- dma-coherent : Present if dma operations are coherent
Example:
ethernet@fff50000 {
compatible = "calxeda,hb-xgmac";
reg = <0xfff50000 0x1000>;
interrupts = <0 77 4 0 78 4 0 79 4>;
};

title: Calxeda Highbank 10Gb XGMAC Ethernet controller
description: |
The Calxeda XGMAC Ethernet controllers are directly connected to the
internal machine "network fabric", which is set up, initialised and
managed by the firmware. So there are no PHY properties in this
binding. Switches in the fabric take care of routing and mapping the
traffic to external network ports.

Can point to at most 3 xgmac interrupts. The 1st one is the main
interrupt, the 2nd one is used for power management. The optional
