Subject: [PATCH net-next 2/2] dt-bindings: net: mediatek,net: move mediatek,mt7621-eth to another schema
The bindings for mediatek,mt7621-eth contradict with some of the rules on
the top level schema of mediatek,net.yaml:
- resets must be two items. resets with "maxItems: 3" at the top level
implies "minItems: 3" and cannot be overriden under a subschema.
- reset-names items must be "fe" and "eth". reset-names items defined on
the top level schema cannot be overridden under a subschema.
Therefore, move mediatek,mt7621-eth to another schema. Fix the order of
clock-names items. Do not define the properties that don't apply to this
hardware. Require more properties. Add an example.
Fixes: 1cbf487d7d3a ("dt-bindings: net: mediatek,net: add missing mediatek,mt7621-eth")
