3This file provides information, what the device node
4for the davinci_emac interface contains.
5
6Required 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
19Optional 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
