- * 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?
- 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
- 34
- 35
- 36
- >;
- interrupt-parent = <&intc>;
- };
