From fe0cd96c009b14cc85d41a97f84a6453e4bbfd7f Mon Sep 17 00:00:00 2001 From: Neil Greatorex Date: Sat, 30 Mar 2013 20:41:20 +0000 Subject: bus: mvebu-mbus: Restore checking for coherency fabric hardware The new mvebu-mbus driver was not checking the device tree for coherency fabric hardware and hence was not setting the hw_io_coherency flag in mbus_state. This prevented the mvsdio driver from operating correctly. This patch restores the check.
