Subject: [PATCH 3.10 04/18] ARM: mvebu: fix NOR bus-width in Armada XP OpenBlocks AX3 Device Tree
Date: Thu, 12 Jun 2014 16:22:08 -0700 [thread overview]
Message-ID: <20140612232213.220119417@linuxfoundation.org> (raw)
In-Reply-To: <20140612232212.960235342@linuxfoundation.org>
3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
commit 6e20bae8a39c40d4e03698e4160bad2d2629062b upstream.
The mvebu-devbus driver had a serious bug, which lead to a 8 bits bus
width declared in the Device Tree being considered as a 16 bits bus
width when configuring the hardware.
This bug in mvebu-devbus driver was compensated by a symetric mistake
in the Armada XP OpenBlocks AX3 Device Tree: a 8 bits bus width was
declared, even though the hardware actually has a 16 bits bus width
connection with the NOR flash.
Now that we have fixed the mvebu-devbus driver to behave according to
its Device Tree binding, this commit fixes the problematic Device Tree
files as well.
This bug was introduced in commit
a7d4f81821f7eec3175f8e23dd6949c71ab2da43 ('ARM: mvebu: Add support for
NOR flash device on Openblocks AX3 board') which was merged in v3.10.
