Merge tag 'omap-cleanup-sparseirq-for-v3.7' into devel-dt
This branch contains changes needed to make omap2+ work properly with sparse IRQ. It also removes dependencies to mach/hardware.h. These help moving things towards ARM single zImage support. This branch is based on a commit in tty-next branch with omap-devel-gpmc-fixed-for-v3.7 and cleanup-omap-tags-for-v3.7 merged in to keep things compiling and sort out some merge conflicts. Conflicts: arch/arm/mach-omap2/omap4-common.c drivers/gpio/gpio-twl4030.c
