[PATCH v6 20/21] ARM: mvebu: Relocate Armada 370/XP DeviceBus device tree nodes
Ezequiel Garcia

Fri Jul 5 17:39:31 EDT 2013
Now that mbus has been added to the device tree, it's possible to
move the DeviceBus out of internal registers, placing it directly
below the mbus. This is a more accurate representation of the hardware.
