Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson: "This is the branch where we usually queue up cleanup efforts, moving drivers out of the architecture directory, header file restructuring, etc. Sometimes they tangle with new development so it's hard to keep it strictly to cleanups. Some of the things included in this branch are: * Atmel SAMA5 conversion to common clock * Reset framework conversion for tegra platforms - Some of this depends on tegra clock driver reworks that are shared with Mike Turquette's clk tree. * Tegra DMA refactoring, which are shared branches with the DMA tree. * Removal of some header files on exynos to prepare for multiplatform" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (169 commits) ARM: mvebu: move Armada 370/XP specific definitions to armada-370-xp.h ARM: mvebu: remove prototypes of non-existing functions from common.h ARM: mvebu: move ARMADA_XP_MAX_CPUS to armada-370-xp.h serial: sh-sci: Rework baud rate calculation serial: sh-sci: Compute overrun_bit without using baud rate algo serial: sh-sci: Remove unused GPIO request code serial: sh-sci: Move overrun_bit and error_mask fields out of pdata serial: sh-sci: Support resources passed through platform resources serial: sh-sci: Don't check IRQ in verify port operation serial: sh-sci: Set the UPF_FIXED_PORT flag serial: sh-sci: Remove duplicate interrupt check in verify port op serial: sh-sci: Simplify baud rate calculation algorithms serial: sh-sci: Remove baud rate calculation algorithm 5 serial: sh-sci: Sort headers alphabetically ARM: EXYNOS: Kill exynos_pm_late_initcall() ARM: EXYNOS: Consolidate selection of PM_GENERIC_DOMAINS for Exynos4 ARM: at91: switch Calao QIL-A9260 board to DT clk: at91: fix pmc_clk_ids data type attriubte PM / devfreq: use inclusion <mach/map.h> instead of <plat/map-s5p.h> ARM: EXYNOS: remove <mach/regs-clock.h> for exynos ...
