This file provides information, what the device node
|
|
for the davinci_emac interface contains.
|
|
|
|
Required properties:
|
|
- compatible: "ti,davinci-dm6467-emac", "ti,am3517-emac" or
|
|
"ti,dm816-emac"
|
|
- reg: Offset and length of the register set for the device
|
|
- ti,davinci-ctrl-reg-offset: offset to control register
|
|
- ti,davinci-ctrl-mod-reg-offset: offset to control module register
|
|
- ti,davinci-ctrl-ram-offset: offset to control module ram
|
|
- ti,davinci-ctrl-ram-size: size of control module ram
|
|
- interrupts: interrupt mapping for the davinci emac interrupts sources:
|
|
4 sources: <Receive Threshold Interrupt
|
|
Receive Interrupt
|
|
Transmit Interrupt
|
|
Miscellaneous Interrupt>
|
|
|
|
Optional properties:
|
|
- phy-handle: See ethernet.txt file in the same directory.
|
|
If absent, davinci_emac driver defaults to 100/FULL.
|
|
- ti,davinci-rmii-en: 1 byte, 1 means use RMII
|
|
- ti,davinci-no-bd-ram: boolean, does EMAC have BD RAM?
|
|
|
|
The MAC address will be determined using the optional properties
|
|
defined in ethernet.txt.
|
|
|
|
Example (enbw_cmc board):
|
|
eth0: emac@1e20000 {
|
|
compatible = "ti,davinci-dm6467-emac";
|
|
reg = <0x220000 0x4000>;
|
|
ti,davinci-ctrl-reg-offset = <0x3000>;
|
|
ti,davinci-ctrl-mod-reg-offset = <0x2000>;
|
|
ti,davinci-ctrl-ram-offset = <0>;
|
|
ti,davinci-ctrl-ram-size = <0x2000>;
|
|
local-mac-address = [ 00 00 00 00 00 00 ];
