2 | |||
3 | This file provides information, what the device node | ||
4 | for the davinci_emac interface contains. | ||
5 | |||
6 | Required properties: | ||
7 | - compatible: "ti,davinci-dm6467-emac"; | ||
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 | ||
13 | - ti,davinci-rmii-en: use RMII | ||
14 | - ti,davinci-no-bd-ram: has the emac controller BD RAM | ||
15 | - phy-handle: Contains a phandle to an Ethernet PHY. | ||
16 | if not, davinci_emac driver defaults to 100/FULL | ||
17 | - interrupts: interrupt mapping for the davinci emac interrupts sources: | ||
18 | 4 sources: <Receive Threshold Interrupt | ||
19 | Receive Interrupt | ||
20 | Transmit Interrupt | ||
21 | Miscellaneous Interrupt> | ||
22 | |||
23 | Optional properties: | ||
24 | - local-mac-address : 6 bytes, mac address | ||
25 | |||
26 | Example (enbw_cmc board): | ||
27 | eth0: emac@1e20000 { | ||
28 | compatible = "ti,davinci-dm6467-emac"; | ||
29 | reg = <0x220000 0x4000>; | ||
30 | ti,davinci-ctrl-reg-offset = <0x3000>; | ||
31 | ti,davinci-ctrl-mod-reg-offset = <0x2000>; | ||
32 | ti,davinci-ctrl-ram-offset = <0>; | ||
33 | ti,davinci-ctrl-ram-size = <0x2000>; | ||
34 | local-mac-address = [ 00 00 00 00 00 00 ]; | ||
