[PATCH v4 net-next 3/5] dt-bindings: net: pcs: mediatek,sgmiisys: deprecate "mediatek,pnswap"

[Vladimir Oltean <vladimir.oltean@nxp.com>]

Reference the common PHY properties, and update the example to use them.
Note that a PCS subnode exists, and it seems a better container of the
polarity description than the SGMIISYS node that hosts "mediatek,pnswap".
So use that.
