[PATCH] ARM: arm64: dts: Add expansion bus to VExpress and Juno

Brian Starkey brian.starkey at arm.com
Mon Apr 4 09:20:50 PDT 2016


The VExpress and Juno development platforms have an external expansion
bus which can be used for additional hardware (e.g. LogicTile Express
daughterboards).
Add this bus to all VExpress CoreTile and Juno device-trees.

On VExpress, the bus is described for a CoreTile located on site 1.
