* Texas Instruments Davinci EMAC
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?
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

interrupt-parent = <&intc>;
