Adding the mdio property to the dsa.yaml schema will allow it on all of the
schemas that refer to dsa.yaml such as this one. This addition here is only
to disallow additional properties under the mdio property for this specific
schema.
That said, my understanding is that the internal MDIO bus exists on all of
the switches controlled by DSA.
How come?
Whether each individual DSA subdriver supports registering it does not
matter in terms of documenting the internal MDIO bus for all DSA
switches.
SJA1110 uses the mdios property instead because it's got two internal mdio
buses, which is why I invalidate the mdio property for it. If SJA1105 has
also got two internal mdio buses, let me know.
SJA1105 has zero internal MDIO buses and zero internal PHYs.
Ah okay. I didn't consider the switch architecture where the data interface
of the PHY is connected to the switch, and the PHY management interface is
connected to the mdio bus that the switch is connected to.
The schemas of the switches which already utilise the mdio property:
- /schemas/net/dsa/microchip,lan937x.yaml
- /schemas/net/dsa/qca8k.yaml
- /schemas/net/dsa/realtek.yaml
- /schemas/net/dsa/renesas,rzn1-a5psw.yaml
The schemas of the switches which don't have an internal MDIO bus, meaning
the mdio property must be invalid:
- /schemas/net/mscc,vsc7514-switch.yaml
- /schemas/net/dsa/nxp,sja1105.yaml
The schemas of the switches which I don't know if the switch has got an
internal MDIO bus:
- /schemas/net/dsa/arrow,xrs700x.yaml
- I believe, because there's phy-handle defined on every port without the
mdio node on the example, the PHYs are not connected to the internal
MDIO bus. Therefore, we can invalidate the mdio property for this
schema.
- /schemas/net/dsa/brcm,b53.yaml
- Seems ok to keep it valid.
- /schemas/net/dsa/brcm,sf2.yaml
- Seems ok to keep it valid.
- /schemas/net/dsa/hirschmann,hellcreek.yaml
- Same as /schemas/net/dsa/arrow,xrs700x.yaml.
- /schemas/net/dsa/microchip,ksz.yaml
- Seems ok to keep it valid.
- /schemas/net/dsa/mscc,ocelot.yaml

Not json-schema documentation, don't care about:
