[PATCH v2 net-next] dt-bindings: net: xilinx: document xilinx emaclite driver binding

[Radhey Shyam Pandey]

Add basic description for the xilinx emaclite driver DT bindings.

Signed-off-by: Radhey Shyam Pandey <radhey.shyam.pandey@amd.com>
---
Changes since v1:
- Move ethernet-controller.yaml reference after maintainers.
- Drop interrupt second cell in example node.
- Set local-mac-address to all 0s in example node.
- Put the reg after compatible in DTS code.

Changes since RFC:
- Add ethernet-controller yaml reference.
- 4 space indent for DTS example.

Even if marked for 'net-next', my understanding is that should go via
the device tree repo. I'm dropping from the netdev patchwork, please
correct me if I'm wrong, thanks!

I have seen a mixed set of the convention for dts patches. They are following
both routes i.e device tree or subsystem repos provided acked from device
tree maintainer.  If there is preference for device tree repo then I can drop
net-next from subject prefix and resend it for the dt repo.

If you got Ack from Devicetree bindings maintainer (Rob Herring or me),
then feel free to take it via net-next. I think, it is actually
preferred, unless this is some fix which needs to go via DT (Rob's) tree.

If you don't have these acks, then better don't take it :) unless it's
really waiting too long on the lists. I hope it's not that case.


Best regards,
Krzysztof

I got this reply in my mailbox but I cannot find at all the original
patch, which might explain why it was not acked. I found it on lore,
though. Rob had here questions but I think you resolved/answered them,
so from my side:

GTK, thanks. I'm also often confused by the correct tree for DT patches.
I'll revive the patch in PW and apply it later today.

It is documented in
Documentation/devicetree/bindings/submitting-patches.rst, section II.

The default is bindings should go thru subsystem trees. Given netdev's
tendency to apply bindings before DT review and even semi-automated
checks, but skipping standalone patches, I haven't minded picking them
up.
