Blank line

Don't put it between properties. For nested object usually this is
before properties:

Skip blank line.

No need for quotes.

Why do you need to mention this property? Isn't it coming from
ethernet-controller.yaml?

This is getting confusing. You have now:
- phy-handle
- phy
- phy-device
- phys
in one schema... although lan966x serdes seems to do the same. :/

No need for quotes. Are you sure this is property of each port? I don't
know the net/ethernet bindings that good, so I need to ask sometimes
basic questions. Other bindings seem to do it differently a bit.

Wrong indentation. Use 4 spaces.

This is not a DSA driver, but a pure switchdev driver. It is similar
to prestera, lan966x, sparx5, which put there binding in net.

As Andrew mentioned, this is not a DSA driver.

Yes... I found the following documents have "phy" and "phy-handle" by using
git grep -l -w "phys" `git grep -l phy-handle Documentation/devicetree/bindings/`:
Documentation/devicetree/bindings/net/cdns,macb.yaml
Documentation/devicetree/bindings/net/cpsw.txt
Documentation/devicetree/bindings/net/microchip,lan966x-switch.yaml
Documentation/devicetree/bindings/net/microchip,sparx5-switch.yaml
Documentation/devicetree/bindings/net/ti,cpsw-switch.yaml
Documentation/devicetree/bindings/net/ti,k3-am654-cpsw-nuss.yaml
Documentation/devicetree/bindings/phy/phy-bindings.txt

And I'm interesting that the phy-bindings.txt said the following:
-----
phys : the phandle for the PHY device (used by the PHY subsystem; not to be
       confused with the Ethernet specific 'phy' and 'phy-handle' properties,
       see Documentation/devicetree/bindings/net/ethernet.txt for these)

Yes, each port has mdio bus.

Don't drop, but instead put it before "properties" for this nested object.

Oh, I got it. Thanks!
I'll put this before "properties:" like below:
-----
  ethernet-ports:
    type: object

    additionalProperties: false

    properties:
      '#address-cells':
        description: Port number of ETHA (TSNA).
        const: 1

      '#size-cells':
        const: 0
