13 - device_type : "network"
15 - compatible : compatible list, contains 2 entries, first is
16 "ibm,emac-CHIP" where CHIP is the host ASIC (440gx,
18 "ibm,emac4". For Axon, thus, we have: "ibm,emac-axon",
20 - interrupts : <interrupt mapping for EMAC IRQ and WOL IRQ>
21 - reg : <registers mapping>
22 - local-mac-address : 6 bytes, MAC address
23 - mal-device : phandle of the associated McMAL node
24 - mal-tx-channel : 1 cell, index of the tx channel on McMAL associated
