Optional properties:
- phy-handle: See ethernet.txt file in the same directory.
If absent, davinci_emac driver defaults to 100/FULL.
- nvmem-cells: phandle, reference to an nvmem node for the MAC address
- nvmem-cell-names: string, should be "mac-address" if nvmem is to be used
- ti,davinci-rmii-en: 1 byte, 1 means use RMII

- nvmem-cells: phandle, reference to an nvmem node for the MAC address;
- nvmem-cell-names: string, should be "mac-address" if nvmem is to be used;
- max-speed: number, specifies maximum speed in Mbit/s supported by the device;
- max-frame-size: number, maximum transfer unit (IEEE defined MTU), rather than
the maximum frame size (there's contradiction in the Devicetree
Specification).
- phy-mode: string, operation mode of the PHY interface. This is now a de-facto
standard property; supported values are:
* "internal"
* "internal" (Internal means there is not a standard bus between the MAC and
the PHY, something proprietary is being used to embed the PHY in the MAC.)
* "mii"
* "gmii"
* "sgmii"
