Subject: Re: [PATCH 2/4] dt-bindings: net: dsa: document internal MDIO bus
I've realised there are more schemas that extend the mdio.yaml schema. This
is the final state of this patch.
dt-bindings: net: dsa: document internal MDIO bus
Add the schema to document the internal MDIO bus. Require the phy-handle
property on the non-CPU ports if the mdio property is being used.
Define the mdio property on all of the schemas that refer to
dsa.yaml#/$defs/ethernet-ports. Refer to dsa.yaml#/properties/mdio to point
the human readers to the description on the dsa.yaml schema.
Some of these schemas extend the mdio.yaml schema. The mdio.yaml schema is
also being referred to through dsa.yaml#/$defs/ethernet-ports now which
means we cannot disallow additional properties by 'unevaluatedProperties:
false' on the dsa.yaml schema.

dt-bindings: net: dsa: nxp,sja1105: improve internal MDIO bus bindings
SJA1110 Ethernet Switch uses the mdios property for its internal MDIO bus.
Therefore, disallow the mdios property for SJA1105, and the mdio property
for SJA1110.
Require the phy-handle property on the non-CPU ports if the mdios property
is being used.
Refer to dsa.yaml#/properties/mdio to point the human readers to the
description on the dsa.yaml schema.
