[PATCH v4 0/1] arm64: dts: mt8195: Add Ethernet controller

[Biao Huang]

Changes in v4:
1. remove {address,size}-cells = <0> to avoid warning as Angelo's feedback.
2. Add reviewd-by as Angelo's comments.

Changes in v3:
1. move stmmac-axi-config, rx-queues-config, tx-queues-configs inside ethernet node
as Angelo's comments.
2. add {address,size}-cells = <0> in ethernet node as Angelo's comments.

Changes in v2:
1. modify pinctrl node used by ethernet to match rules in pinctrl-mt8195.yaml,
which is pointed by Krzysztof.
2. remove "mac-address" property in ethernet node as comments of Krzysztof.

Changes in v1:
add dts node for MT8195 Ethernet controller

Dear Matthias,

Biao also found this patch for ethernet node seems missing in 6.2 dts 
pull-request.

Just a remind for this patch.
Please help to review this patch if you have time.
Thanks!
