Subject: [PATCH RFC net-next 16/23] net: dsa: lantiq_gswip: support standard MDIO node name
Date: Sat, 16 Aug 2025 20:55:27 +0100 [thread overview]
Message-ID: <aKDiL76zC3ZiwQHk@pidgin.makrotopia.org> (raw)
Instead of matching against the child node's compatible string also
support locating the node of the device tree node of the MDIO bus
in the standard way by referencing the node name ("mdio").
