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", "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
20 Optional 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
26 The MAC address will be determined using the optional properties
27 defined in ethernet.txt.

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 ];
