Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson: "A large cleanup branch this release, with a healthy 10k negative line delta. Most of this is removal of legacy (non-DT) support of shmobile platforms. There is also removal of two non-DT platforms on OMAP, and the plat-samsung directory is cleaned out by moving most of the previously shared-location-but-not-actually-shared files from there to the appropriate mach directories instead. There are other sets of changes in here as well: - Rob Herring removed use of set_irq_flags under all platforms and moved to genirq alternatives - a series of timer API conversions to set-state interface - ep93xx, nomadik and ux500 cleanups from Linus Walleij - __init annotation fixes from Nicolas Pitre + a bunch of other changes that all add up to a nice set of cleanups" * tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (108 commits) ARM/fb: ep93xx: switch framebuffer to use modedb only ARM: gemini: Setup timer3 as free running timer ARM: gemini: Use timer1 for clockevent ARM: gemini: Add missing register definitions for gemini timer ARM: ep93xx/timer: Migrate to new 'set-state' interface ARM: nomadik: push accelerometer down to boards ARM: nomadik: move l2x0 setup to device tree ARM: nomadik: selectively enable UART0 on boards ARM: nomadik: move hog code to use DT hogs ARM: shmobile: Fix mismerges ARM: ux500: simplify secondary CPU boot ARM: SAMSUNG: remove keypad-core header in plat-samsung ARM: SAMSUNG: local watchdog-reset header in mach-s3c64xx ARM: SAMSUNG: local onenand-core header in mach-s3c64xx ARM: SAMSUNG: local irq-uart header in mach-s3c64xx ARM: SAMSUNG: local backlight header in mach-s3c64xx ARM: SAMSUNG: local ata-core header in mach-s3c64xx ARM: SAMSUNG: local regs-usb-hsotg-phy header in mach-s3c64xx ARM: SAMSUNG: local spi-core header in mach-s3c24xx ARM: SAMSUNG: local nand-core header in mach-s3c24xx ...
