This is a backport of the patches accepted to the Linux mainline related to mvebu SoC (Armada XP and Armada 370) between Linux v3.11, and Linux v3.12. This work mainly covers: * Ground work for sharing the pxa nand driver(drivers/mtd/nand/pxa3xx_nand.c) between the PXA family,and the Armada family. * Further updates to the mvebu MBus. * Work and ground work for enabling MSI on the Armada family. * some phy / mdio bus initialization related work. * Device tree binding documentation update.

Subject: [PATCH 054/203] ARM: mvebu: Initialize MBus using the DT binding
|
|
|
|
Now that the mbus device tree binding has been introduced, we can
|
|
switch over to it.
|
|
|
|
Also, and since the initialization of the mbus driver is quite
|
|
fundamental for the system to work properly, this patch adds a BUG()
|
|
in case mbus fails to initialize.
