Petr Štetiar 687e3d5550 dt-bindings: doc: reflect new NVMEM of_get_mac_address behaviour
As of_get_mac_address now supports NVMEM under the hood, we need to update
the bindings documentation with the new nvmem-cell* properties, which would
mean copy&pasting a lot of redundant information to every binding
documentation currently referencing some of the MAC address properties.

So I've just removed all the references to the optional MAC address
properties and replaced them with the small note referencing
net/ethernet.txt file.

* 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>;
};
