Subject: [PATCH 043/203] 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.
