Merge tag 'omap-cleanup-sparseirq-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup
From Tony Lindgren:
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.
* tag 'omap-cleanup-sparseirq-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP1: Move SoC specific headers from plat to mach for omap1
ARM: OMAP2+ Move SoC specific headers to be local to mach-omap2
ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+
ARM: OMAP: Remove unused old gpio-switch.h
ARM: OMAP1: Move plat/irqs.h to mach/irqs.h
ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ
ARM: OMAP2+: Prepare for irqs.h removal
W1: OMAP HDQ1W: Remove dependencies to mach/hardware.h
Input: omap-keypad: Remove dependencies to mach includes
ARM: OMAP: Move gpio.h to include/linux/platform_data
ARM: OMAP2+: Remove hardcoded twl4030 gpio_base, irq_base and irq_end
ARM: OMAP2+: Remove unused nand_irq for GPMC
ARM: OMAP2+: Make INTCPS_NR_IRQS local for mach-omap2/irq.c
ARM: OMAP1: Define OMAP1_INT_I2C locally
ARM: OMAP1: Move define of OMAP_LCD_DMA to dma.h
