Raw Blame History

From bcb0e54d62804f1f986ad478a11235dadb1b61bb Mon Sep 17 00:00:00 2001
From: Ezequiel Garcia <ezequiel.garcia@free-electrons.com>
Date: Fri, 14 Jun 2013 10:44:57 -0300
Subject: [PATCH 058/203] ARM: mvebu: Relocate Armada 370/XP DeviceBus device
tree nodes
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.
