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?

32 ti,davinci-ctrl-ram-offset = <0>;
33 ti,davinci-ctrl-ram-size = <0x2000>;
