3This file provides information, what the device node
4for the davinci_emac interface contains.

6Required properties:
7- compatible: "ti,davinci-dm6467-emac";
8- reg: Offset and length of the register set for the device
9- ti,davinci-ctrl-reg-offset: offset to control register
10- ti,davinci-ctrl-mod-reg-offset: offset to control module register
11- ti,davinci-ctrl-ram-offset: offset to control module ram
12- ti,davinci-ctrl-ram-size: size of control module ram
13- ti,davinci-rmii-en: use RMII
14- ti,davinci-no-bd-ram: has the emac controller BD RAM
15- phy-handle: Contains a phandle to an Ethernet PHY.
16              if not, davinci_emac driver defaults to 100/FULL
17- interrupts: interrupt mapping for the davinci emac interrupts sources:
18              4 sources: <Receive Threshold Interrupt
19			  Receive Interrupt
20			  Transmit Interrupt
21			  Miscellaneous Interrupt>
