1 | * Texas Instruments Davinci EMAC |
| 2 | ||
| 3 | This file provides information, what the device node | |
| 4 | for the davinci_emac interface contains. | |
| 5 | ||
| 6 | Required properties: | |
| dd0df47d | 7 | - compatible: "ti,davinci-dm6467-emac" or "ti,am3517-emac" |
| 42f59967 HS |
8 | - reg: Offset and length of the register set for the device |
| 9 | - ti,davinci-ctrl-reg-offset: offset to control register | |
| 10 | - ti,davinci-ctrl-mod-reg-offset: offset to control module register | |
| 11 | - ti,davinci-ctrl-ram-offset: offset to control module ram | |
| 12 | - ti,davinci-ctrl-ram-size: size of control module ram | |
| 42f59967 | 13 | - ti,davinci-no-bd-ram: has the emac controller BD RAM |
| 42f59967 HS |
14 | - interrupts: interrupt mapping for the davinci emac interrupts sources: |
| 15 | 4 sources: <Receive Threshold Interrupt | |
| 16 | Receive Interrupt | |
| 17 | Transmit Interrupt | |
| 18 | Miscellaneous Interrupt> | |
| 19 | ||
| 20 | Optional properties: | |
| 2c2dc161 SS |
21 | - phy-handle: Contains a phandle to an Ethernet PHY. |
| 22 | If absent, davinci_emac driver defaults to 100/FULL. | |
| 42f59967 | 23 | - local-mac-address : 6 bytes, mac address |
| 731ff244 | 24 | - ti,davinci-rmii-en: 1 byte, 1 means use RMII |

| 26 | Example (enbw_cmc board): | |
| 27 | eth0: emac@1e20000 { | |
