Subject: ARM: mvebu: fix NOR bus-width in Armada XP DB Device Tree
From: Thomas Petazzoni <thomas.petazzoni@xxxxxxxxxxxxxxxxxx>
commit f3aec8f3f05025e7b450102dae0759375346706e 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 DB 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
b484ff42df475c5087d614c4d477273e1906bcb9 ('ARM: mvebu: Add support for
NOR flash device on Armada XP-DB board') which was merged in v3.11.
