+- reg: Address and length of the register set for the device. It contains the

+- 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.
