| Subject | [PATCH v3 1/2] ARM: dts: Add expansion bus to VExpress |
| Message-ID | <rnRx7-408-7@gated-at.bofh.it> |
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.
