1	* Texas Instruments Davinci EMAC
2	
3	This file provides information, what the device node
4	for the davinci_emac interface contains.
5	
6	Required properties:
7	- compatible: "ti,davinci-dm6467-emac" or "ti,am3517-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>
22	
23	Optional properties:
24	- local-mac-address : 6 bytes, mac address
25	
26	Example (enbw_cmc board):
27		eth0: emac@1e20000 {
28			compatible = "ti,davinci-dm6467-emac";
29			reg = <0x220000 0x4000>;
30			ti,davinci-ctrl-reg-offset = <0x3000>;
31			ti,davinci-ctrl-mod-reg-offset = <0x2000>;
32			ti,davinci-ctrl-ram-offset = <0>;
33			ti,davinci-ctrl-ram-size = <0x2000>;
34			local-mac-address = [ 00 00 00 00 00 00 ];
35			interrupts = <33
