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 time around, the cleanup branch contains mostly code removal. A number of board files for at91, imx and msm have become obsolete because of the DT conversion and are now ready to be removed. The OMAP platform has traditionally had its own DMA engine abstraction and as this is being phased out, a lot of the original code is now unused and can be removed as well. S3C24xx can be simplified now that the restart code is a proper device driver. Finally, a number of cleanups in shmobile are done to prepare for the addition of new code in other branches" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (43 commits) ARM: at91: Remove the support for the RSI EWS board arm: mach-omap2: Convert pr_warning to pr_warn ARM: OMAP: Remove unused pieces of legacy DMA API ARM: at91: remove board file for Acme Systems Fox G20 ARM: orion5x: Convert pr_warning to pr_warn ARM: S3C24XX: remove separate restart code ARM: EXYNOS: Do not calculate boot address twice ARM: sunxi: Remove sun4i reboot code from mach directory ARM: imx: Remove mach-mxt_td60 board file ARM: shmobile: armadillo800eva legacy: Use rmobile_add_devices_to_domains() ARM: shmobile: r8a7740: Clean up pm domain table ARM: shmobile: r8a7740: Use rmobile_add_devices_to_domains() ARM: shmobile: sh7372: Make domain_devices[] static __initdata ARM: shmobile: mackerel: Make domain_devices[] static __initdata clocksource: tcb_clksrc: sanitize IRQ request ARM: at91/tclib: mask interruptions at shutdown and probe ARM: at91/tclib: move initialization from alloc to probe ARM: at91/tclib: prefer using of devm_* functions ARM: clps711x: Switch CLPS711X subarch to use clk and clocksource driver ARM: shmobile: r8a7791 is now called "R-Car M2-W" ...
