[PATCH v3 1/2] ARM: dts: Add expansion bus to VExpress

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




The VExpress development platform has an external expansion bus which
can be used for additional hardware (e.g. LogicTile Express
daughterboards).
Add this bus to the VExpress CoreTile device-trees.

The bus is described for a CoreTile occupying site 1.
