Subject: [PATCH RESEND net-next 1/2] net: dsa: mt7530: register OF node for
internal MDIO bus
From: David Bauer <mail@...id-bauer.net>
The MT753x switches provide a switch-internal MDIO bus for the embedded
PHYs.
Register a OF sub-node on the switch OF-node for this internal MDIO bus.
This allows to configure the embedded PHYs using device-tree.
