Subject: [PATCH v2 05/14] bus: mvebu-mbus: Remove coherency attribute
Date: Mon, 20 Apr 2015 22:11:17 +0200	[thread overview]
Message-ID: <1429560686-11391-6-git-send-email-sebastian.hesselbarth@gmail.com> (raw)
In-Reply-To: <1429560686-11391-1-git-send-email-sebastian.hesselbarth@gmail.com>

Marvell Armada 370 and XP have some coherency fabric. We are not
interested in using it, so remove checking for it in mbus driver.
