-- 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.

+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.
