1* Texas Instruments Davinci EMAC

3This file provides information, what the device node
4for the davinci_emac interface contains.
5
6Required properties:
7- compatible: "ti,davinci-dm6467-emac", "ti,am3517-emac" or
8  "ti,dm816-emac"
9- reg: Offset and length of the register set for the device
10- ti,davinci-ctrl-reg-offset: offset to control register
11- ti,davinci-ctrl-mod-reg-offset: offset to control module register
12- ti,davinci-ctrl-ram-offset: offset to control module ram
13- ti,davinci-ctrl-ram-size: size of control module ram
14- interrupts: interrupt mapping for the davinci emac interrupts sources:
15              4 sources: <Receive Threshold Interrupt
16			  Receive Interrupt
17			  Transmit Interrupt
18			  Miscellaneous Interrupt>
19
20Optional properties:
21- phy-handle: See ethernet.txt file in the same directory.
22              If absent, davinci_emac driver defaults to 100/FULL.
23- ti,davinci-rmii-en: 1 byte, 1 means use RMII
24- ti,davinci-no-bd-ram: boolean, does EMAC have BD RAM?
25
26The MAC address will be determined using the optional properties
27defined in ethernet.txt.

29Example (enbw_cmc board):
30	eth0: emac@1e20000 {
31		compatible = "ti,davinci-dm6467-emac";
32		reg = <0x220000 0x4000>;
33		ti,davinci-ctrl-reg-offset = <0x3000>;
34		ti,davinci-ctrl-mod-reg-offset = <0x2000>;
35		ti,davinci-ctrl-ram-offset = <0>;
36		ti,davinci-ctrl-ram-size = <0x2000>;
37		local-mac-address = [ 00 00 00 00 00 00 ];
38		interrupts = <33
39				34
40				35
41				36
42				>;
43		interrupt-parent = <&intc>;
44	};
