|
- 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 ]; |
|
interrupts = <33 |
