From 3af779eb172b0438f77e8a01a97dd0eb9a146076 Mon Sep 17 00:00:00 2001 From: Luka Perkov Date: Tue, 11 Feb 2014 02:07:41 +0000 Subject: mvebu: backport mainline patches from kernel 3.12 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.
