+* 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";
+- 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
+- ti,davinci-rmii-en: use RMII
+- ti,davinci-no-bd-ram: has the emac controller BD RAM
+- phy-handle: Contains a phandle to an Ethernet PHY.
+ if not, davinci_emac driver defaults to 100/FULL
+- interrupts: interrupt mapping for the davinci emac interrupts sources:
+ 4 sources: <Receive Threshold Interrupt
+ Receive Interrupt
+ Transmit Interrupt
+ Miscellaneous Interrupt>
+
+Optional properties:
+- local-mac-address : 6 bytes, mac address
+
+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
+ 34
+ 35

+ >;
+ interrupt-parent = <&intc>;
+ };
