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	- interrupts: interrupt mapping for the davinci emac interrupts sources:
14	              4 sources: <Receive Threshold Interrupt
15				  Receive Interrupt
16				  Transmit Interrupt
17				  Miscellaneous Interrupt>
18	
19	Optional properties:
20	- phy-handle: See ethernet.txt file in the same directory.
21	              If absent, davinci_emac driver defaults to 100/FULL.
22	- ti,davinci-rmii-en: 1 byte, 1 means use RMII
23	- ti,davinci-no-bd-ram: boolean, does EMAC have BD RAM?
24	
25	Example (enbw_cmc board):
26		eth0: emac@1e20000 {
27			compatible = "ti,davinci-dm6467-emac";
28			reg = <0x220000 0x4000>;
29			ti,davinci-ctrl-reg-offset = <0x3000>;
30			ti,davinci-ctrl-mod-reg-offset = <0x2000>;
31			ti,davinci-ctrl-ram-offset = <0>;
32			ti,davinci-ctrl-ram-size = <0x2000>;
33			local-mac-address = [ 00 00 00 00 00 00 ];
34			interrupts = <33
35					34
36					35
37					36
38					>;
39			interrupt-parent = <&intc>;
