This is a backport of the patches accepted to the Linux mainline related to mvebu SoC (Armada XP and Armada 370) between Linux v3.10, and Linux v3.11. This work mainly covers: * Enabling USB storage, and PCI to mvebu_defconfig. * Add support for NOR flash. * Some PCI device tree related updates, and bus parsing. * Adding Armada XP & 370 PCI driver, and update some clock gating specifics. * Introduce Marvell EBU Device Bus driver. * Enaling USB in the armada*.dts. * Enabling, and updating the mvebu-mbus. * Some SATA and Ethernet related fixes.

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.
