From: Michal Simek Date: Tue, 27 Aug 2013 10:04:39 +0000 (+0200) Subject: microblaze: timer: Replace microblaze_ prefix by xilinx_ X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5955563ae2ff85e6ae30a2dc8c3ba071edeee957;p=linux-beck.git microblaze: timer: Replace microblaze_ prefix by xilinx_ The main reason that this driver can be used by ARM and PPC. The part of preparing of move to generic location.
