* 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.
