1* Texas Instruments Davinci EMAC 2 3This file provides information, what the device node 4for the davinci_emac interface contains. 5 6Required properties: 7- compatible: "ti,davinci-dm6467-emac", "ti,am3517-emac" or 8 "ti,dm816-emac" 9- reg: Offset and length of the register set for the device 10- ti,davinci-ctrl-reg-offset: offset to control register 11- ti,davinci-ctrl-mod-reg-offset: offset to control module register 12- ti,davinci-ctrl-ram-offset: offset to control module ram 13- ti,davinci-ctrl-ram-size: size of control module ram 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 20Optional properties: 21- phy-handle: See ethernet.txt file in the same directory. 22 If absent, davinci_emac driver defaults to 100/FULL. 23- ti,davinci-rmii-en: 1 byte, 1 means use RMII 24- ti,davinci-no-bd-ram: boolean, does EMAC have BD RAM? 25 26The MAC address will be determined using the optional properties 27defined in ethernet.txt. 28 29Example (enbw_cmc board): 30 eth0: emac@1e20000 { 31 compatible = "ti,davinci-dm6467-emac"; 32 reg = <0x220000 0x4000>; 33 ti,davinci-ctrl-reg-offset = <0x3000>; 34 ti,davinci-ctrl-mod-reg-offset = <0x2000>; 35 ti,davinci-ctrl-ram-offset = <0>; 36 ti,davinci-ctrl-ram-size = <0x2000>; 37 local-mac-address = [ 00 00 00 00 00 00 ]; 38 interrupts = <33 39 34 40 35 41 36 42 >; 43 interrupt-parent = <&intc>; 44 };
