From 6bd6b3cb82d55e3b9f3080b6d2c648ceffc7b08a Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Fri, 26 Jul 2013 10:17:44 -0300 Subject: bus: mvebu-mbus: Factor out initialization details We introduce a common initialization function mvebu_mbus_common_init() that will be used by both legacy and device-tree initialization code. This patch is an intermediate step, which will allow to introduce the DT binding for this driver in a less intrusive way.
