Merge tag 'headers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC Header cleanups from Olof Johansson: "This is a collection of header file cleanups, mostly for OMAP and AT91, that keeps moving the platforms in the direction of multiplatform by removing the need for mach-dependent header files used in drivers and other places." Fix up mostly trivial conflicts as per Olof. * tag 'headers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (106 commits) ARM: OMAP2+: Move iommu/iovmm headers to platform_data ARM: OMAP2+: Make some definitions local ARM: OMAP2+: Move iommu2 to drivers/iommu/omap-iommu2.c ARM: OMAP2+: Move plat/iovmm.h to include/linux/omap-iommu.h ARM: OMAP2+: Move iopgtable header to drivers/iommu/ ARM: OMAP: Merge iommu2.h into iommu.h atmel: move ATMEL_MAX_UART to platform_data/atmel.h ARM: OMAP: Remove omap_init_consistent_dma_size() arm: at91: move at91rm9200 rtc header in drivers/rtc arm: at91: move reset controller header to arm/arm/mach-at91 arm: at91: move pit define to the driver arm: at91: move at91_shdwc.h to arch/arm/mach-at91 arm: at91: move board header to arch/arm/mach-at91 arn: at91: move at91_tc.h to arch/arm/mach-at91 arm: at91 move at91_aic.h to arch/arm/mach-at91 arm: at91 move board.h to arch/arm/mach-at91 arm: at91: move platfarm_data to include/linux/platform_data/atmel.h arm: at91: drop machine defconfig ARM: OMAP: Remove NEED_MACH_GPIO_H ARM: OMAP: Remove unnecessary mach and plat includes ...
