dropping this (and address-cells/size-cells from examples) causes errors like this (address-/size-cells set in mdio
node, so imho it should inherite):
Documentation/devicetree/bindings/net/dsa/mediatek,mt7530.example.dts:34.25-35: Warning (reg_format):
/example-0/mdio/switch@0/ports/port@0:reg: property has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)

imho this will block address-/size-cells from this level too. looks like it is needed here too (for port-regs).

ok, i will change this

current implementation in all existing dts and examples from old binding are "ports" only.
should they changed too?
