Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Arnd Bergmann: "This contains cleanups as preparation for other branches adding new features, we pulled 16 branches for 9 platforms into this one. Most notable here is the removal of support for ATAGS based OMAP4 systems. Since all OMAP4 machines are fully functional with DT based booting in 3.10, we can remove a lot of code here. Also noteworthy is Maxime Ripard's cleanup of the machine descriptors, which means we need no machine descriptors in a lot more cases and can boot additional machines by just having the respective device drivers enabled." * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (76 commits) ARM: picoxcell: remove .nr_irqs reference ARM: s5p64x0: avoid build warning for uncompress.h ARM: SAMSUNG: Remove unused plat/regs-watchdog.h header ARM: SAMSUNG: Remove legacy watchdog reset code ARM: SAMSUNG: Let platforms use the new watchdog reset driver ARM: SAMSUNG: Add watchdog reset driver ARM: SAMSUNG: Use local definitions of watchdog registers watchdog: s3c2410_wdt: Use local register definitions ARM: S5P64X0: Use common uncompress.h part for plat-samsung ARM: SAMSUNG: Consolidate uncompress subroutine ARM: at91: drop rm9200dk board support ARM: dts: msm: Fix merge resolution ARM: OMAP1: Remove dma.h ARM: OMAP1: Remove legacy irda.h and irda setup from board files ARM: OMAP1: Remove duplicated DMA channel definitions ARM: OMAP1: Remove McBSP DMA channel definitions ARM: OMAP2+: Remove dma.h ARM: OMAP2+: hwmod: Remove remaining DMA channel definitions ARM: OMAP2+: Remove duplicated DMA channel definitions ARM: OMAP2+: Remove AES crypto device DMA channel definitions ...
