DT: net: document Ethernet bindings in one place This patch is an attempt to gather the Ethernet related bindings in one file, like it's done in the MMC and some other subsystems. It should save some of the trouble of documenting several properties over and over in each binding document, instead only making reference to the main file. I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR) standard as a base for the properties description, also documenting some ad-hoc properties that have been introduced over time despite having direct analogs in ePAPR.

- phy-handle: See ethernet.txt file in the same directory.
DT: net: davinci_emac: "phy-handle" property is actually optional Though described as required, the "phy-handle" property for the DaVinci EMAC binding is actually optional, as the driver will happily function without it, assuming 100/FULL link; the property is not specified either in the example device node, or in the actual EMAC device nodes for DA850 and AM3517 device trees.

If absent, davinci_emac driver defaults to 100/FULL.
DT: net: davinci_emac: "ti, davinci-rmii-en" property is actually optional Though described as required, the "ti,davinci-rmii-en" property for the DaVinci EMAC binding seems actually optional, as the driver should happily work without it; the property is not specified either in the example device node or in the actual EMAC device node for DA850 device tree, only AM3517 one. While at it, document the property better... Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: David S. Miller <davem@davemloft.net>

- ti,davinci-rmii-en: 1 byte, 1 means use RMII
DT: net: davinci_emac: "ti, davinci-no-bd-ram" property is actually optional The "ti,davinci-no-bd-ram" property for the DaVinci EMAC binding simply can't be required one, as it's boolean (which means it's absent if false).

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.

The MAC address will be determined using the optional properties
defined in ethernet.txt.
