From c9ae111a20be4c9555128cced8edded660d133df Mon Sep 17 00:00:00 2001 From: Luka Perkov Date: Tue, 11 Feb 2014 02:07:44 +0000 Subject: mvebu: backport mainline patches from kernel 3.13 This is a backport of the patches accepted to the Linux mainline related to mvebu SoC (Armada XP and Armada 370) between Linux v3.12, and Linux v3.13. This work mainly covers: * Finishes work for sharing the pxa nand driver(drivers/mtd/nand/pxa3xx_nand.c) between the PXA family, and the Armada family. * timer initialization update, and access function for the Armada family. * Generic IRQ handling backporting. * Some bug fixes.
