 * NI XGE Ethernet controller
 
 Required properties:
-- compatible: Should be "ni,xge-enet-2.00"
-- reg: Address and length of the register set for the device
+- compatible: Should be "ni,xge-enet-3.00", but can be "ni,xge-enet-2.00" for
+              older device trees with DMA engines co-located in the address map,
+              with the one reg entry to describe the whole device.
+- reg: Address and length of the register set for the device. It contains the
+       information of registers in the same order as described by reg-names.
+- reg-names: Should contain the reg names
+	"dma":  DMA engine control and status region
+        "ctrl": MDIO and PHY control and status region
 - interrupts: Should contain tx and rx interrupt
 - interrupt-names: Should be "rx" and "tx"
 - phy-mode: See ethernet.txt file in the same directory.
