Merge tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC multiplatform code updates from Arnd Bergmann: "This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts. Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only. Both of these platforms are now multiplatform. Finally, a couple of patches from Russell for Dove PMU, and a fix from Valentin Rothberg for Exynos ADC, which were rebased on top of the series to avoid conflicts" * tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (75 commits) ARM: realview: don't select SMP_ON_UP for UP builds ARM: s3c: simplify s3c_irqwake_{e,}intallow definition ARM: s3c64xx: fix pm-debug compilation iio: exynos-adc: fix irqf_oneshot.cocci warnings ARM: realview: build realview-dt SMP support only when used ARM: realview: select apropriate targets ARM: realview: clean up header files ARM: realview: make all header files local ARM: no longer make CPU targets visible separately ARM: integrator: use explicit core module options ARM: realview: enable multiplatform ARM: make default platform work for NOMMU ARM: debug-ll: move DEBUG_LL_UART_EFM32 to correct Kconfig location ARM: defconfig: use correct debug_ll settings ARM: versatile: convert to multi-platform ARM: versatile: merge mach code into a single file ARM: versatile: switch to DT only booting and remove legacy code ARM: versatile: add DT based PCI detection ARM: pxa: mark ezx structures as __maybe_unused ARM: pxa: mark raumfeld init functions as __maybe_unused ...
