From 5955563ae2ff85e6ae30a2dc8c3ba071edeee957 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Tue, 27 Aug 2013 12:04:39 +0200 Subject: [PATCH] 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.
