Subject: [PATCH] dt-bindings: net: davinci_emac: Convert to yaml version from txt
The davinci_emac is used by several devices which are still maintained,
but to make some improvements, it's necessary to convert from txt to yaml.

-* 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@...0000 {
- 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>;
- };
