Subject: [PATCH 1/2] mt7530: register OF node for internal MDIO bus
|
|
|
|
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.
|
|
