[PATCH 0/2] Enable Ethernet on the Genio 700 EVK board

[Nícolas F. R. A. Prado]

The patches in this series add the ethernet node on mt8188 and enable it
on the Genio 700 EVK board.

The changes were picked up from the downstream branch at
https://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-mtk/+git/jammy,
cleaned up and split into two commits.

Can you set phy-mode to rgmii-id, and remove the tx-delay-ps property?

			clock-names = "axi", "apb", "mac_main", "ptp_ref",
				      "rmii_internal", "mac_cg";

Since we can compress clock-names, we should just do that :-)

Well, the MDIO bus is part of the IP anyway, so I think we can just put it here.

			eth_mdio: mdio {
				compatible = "snps,dwmac-mdio";
				#address-cells = <1>;
				#size-cells = <0>;
			};

Please reorder:
				snps,blen = <0 0 0 0 16 8 4>;
				snps,rd_osr_lmt = <0x7>;
				snps,wr_osr_lmt = <0x7>;

1000Gbps? NVIDIA needs to watch out.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
