Pull ARM updates from Russell King: "This contains the usual updates from other people (listed below) and the usual random muddle of miscellaneous ARM updates which cover some low priority bug fixes and performance improvements. I've started to put the pull request wording into the merge commits, which are: - NoMMU stuff: This includes the following series sent earlier to the list: - nommu-fixes - R7 Support - MPU support I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I were discussing today until we've reached a conclusion/that's had some more review. This is rebased (and re-tested) on your devel-stable branch because otherwise there were going to be conflicts with Uwe's V7M work now that you've merged that. I've included the fix for limiting MPU to CPU_V7. - Huge page support These changes bring both HugeTLB support and Transparent HugePage (THP) support to ARM. Only long descriptors (LPAE) are supported in this series. The code has been tested on an Arndale board (Exynos 5250). - LPAE updates Please pull these miscellaneous LPAE fixes I've been collecting for a while now for 3.11. They've been tested and reviewed by quite a few people, and most of the patches are pretty trivial. -- Will Deacon. - arch_timer cleanups Please pull these arch_timer cleanups I've been holding onto for a while. They're the same as my last posting, but have been rebased to v3.10-rc3. - mpidr linearisation (multiprocessor id register - identifies which CPU number we are in the system) This patch series that implements MPIDR linearization through a simple hashing algorithm and updates current cpu_{suspend}/{resume} code to use the newly created hash structures to retrieve context pointers. It represents a stepping stone for the implementation of power management code on forthcoming multi-cluster ARM systems.

2013-06-25Merge branch 'sti/soc' into next/lateOlof Johansson
From Srinivas Kandagatla <srinivas.kandagatla@st.com>: This patch-set adds basic support for STMicroelectronics STi series SOCs which includes STiH415 and STiH416 with B2000 and B2020 board support. STiH415 and STiH416 are dual-core ARM Cortex-A9 CPU, designed for use in Set-top-boxes. The SOC support is available in mach-sti which contains support code for STiH415, STiH416 SOCs including the generic board support. The reason for adding two SOCs at this patch set is to show that no new C code is required for second SOC(STiH416) support. * sti/soc: ARM: stih41x: Add B2020 board support ARM: stih41x: Add B2000 board support ARM: sti: Add DEBUG_LL console support ARM: sti: Add STiH416 SOC support ARM: sti: Add STiH415 SOC support Signed-off-by: Olof Johansson <olof@lixom.net>

2013-04-19Merge branch 'samsung/exynos-multiplatform' into next/multiplatformArnd Bergmann
These patches get us closer to adding multiplatform support on the Exynos platform, they are part of a longer series of patches. This would get all the simple stuff out of the way, and I don't think there is a big risk of introducing regressions with these. A lot of the other patches have already been merged into subsystem trees. After this series in in arm-soc, what is left comes down to * The ASoC conversion to dmaengine won't make it unless someone who knows that code better steps up to do it right away. This means that we won't have audio in a 3.10 multiplatform kernel on Exynos, but it will still work for users that don't enable multiplatform. * The irqchip (combiner), clk and clksource patches are all based on top of other changesets we pulled in from your trees, so I would not make them part of the next/multiplatform branch. We can apply them on top of the next/drivers branch once they are tested successfully. * A trivial patch is needed in the end to actually make CONFIG_ARCH_EXYNOS visible in multiplatform configurations.

2013-03-19ARM: imx: add dependency check for DEBUG_IMX_UART_PORTShawn Guo
While adding i.MX DEBUG_LL selection, commit f8c95fe (ARM: imx: support DEBUG_LL uart port selection for all i.MX SoCs) leaves Kconfig symbol DEBUG_IMX_UART_PORT there without any dependency check. This results in that everyone gets the symbol in their config, which is someting undesirable. Add "depends on ARCH_MXC" for the symbol to prevent that.

I've looked at all the platforms recently to see what their state is. cns3xxx seems quite clean but not very actively maintained.

2013-03-15ARM: 7672/1: uncompress debug support for multiplatform buildShawn Guo
Instead of giving zero support of uncompress debug for multiplatform build, the patch turns uncompress debug into one part of DEBUG_LL support. When DEBUG_LL is turned on for a particular platform, uncompress debug works too for that platform. OMAP and Tegra are exceptions here. OMAP low-level debug code places data in the .data section, and that is not allowed in decompressor. And Tegra code has reference to variable that's unavailable in decompressor but only in kernel. That's why Kconfig symbol DEBUG_UNCOMPRESS controlling multiplatform uncompress debug support is defined with !DEBUG_OMAP2PLUS_UART && !DEBUG_TEGRA_UART. It creates arch/arm/boot/compressed/debug.S with CONFIG_DEBUG_LL_INCLUDE included there, implements a generic putc() using those macros, which will be built when DEBUG_UNCOMPRESS is defined.

2013-03-15ARM: 7671/1: use Kconfig to select uncompress.hShawn Guo
Following the approach handling DEBUG_LL inclusion, the patch creates a Kconfig symbol CONFIG_UNCOMPRESS_INCLUDE for choosing the correct uncompress header. For traditional build, mach/uncompress.h will be included in arch/arm/boot/compressed/misc.c. For multiplatform build, debug/uncompress.h which contains a suite of empty functions will be used. In this way, a platform with particular uncompress.h implementation could choose its own uncompress.h with this Kconfig option.

2013-03-12ARM: bcm2835: convert to multi-platformStephen Warren
This allows BCM2835 be included in a kernel build that supports multiple SoCs at once, which is useful for distro kernels. This change: * Moves bcm2835's debug-macro.S into ARM's include/debug/, and hooks it into the relevant menu. * Moves bcm2835's Kconfig into its own directory, as seems typical for multi-platform conversions. * Removes bcm2835_soc.h, and moves the content to the files where it was used; just one usage per define. * Deletes some headers and Makefile.boot that aren't needed now that we support multi-platform.

Pull ARM SoC cleanups from Arnd Bergmann: "A large number of cleanups, all over the platforms. This is dominated largely by the Samsung platforms (s3c, s5p, exynos) and a few of the others moving code out of arch/arm into more appropriate subsystems. The clocksource and irqchip drivers are now abstracted to the point where platforms that are already cleaned up do not need to even specify the driver they use, it can all get configured from the device tree as we do for normal device drivers. The clocksource changes basically touch every single platform in the process. We further clean up the use of platform specific header files here, with the goal of turning more of the platforms over to being "multiplatform" enabled, which implies that they cannot expose their headers to architecture independent code any more. It is expected that no functional changes are part of the cleanup. The overall reduction in total code lines is mostly the result of removing broken and obsolete code." * tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (133 commits) ARM: mvebu: correct gated clock documentation ARM: kirkwood: add missing include for nsa310 ARM: exynos: move exynos4210-combiner to drivers/irqchip mfd: db8500-prcmu: update resource passing drivers/db8500-cpufreq: delete dangling include ARM: at91: remove NEOCORE 926 board sunxi: Cleanup the reset code and add meaningful registers defines ARM: S3C24XX: header mach/regs-mem.h local ARM: S3C24XX: header mach/regs-power.h local ARM: S3C24XX: header mach/regs-s3c2412-mem.h local ARM: S3C24XX: Remove plat-s3c24xx directory in arch/arm/ ARM: S3C24XX: transform s3c2443 subirqs into new structure ARM: S3C24XX: modify s3c2443 irq init to initialize all irqs ARM: S3C24XX: move s3c2443 irq code to irq.c ARM: S3C24XX: transform s3c2416 irqs into new structure ARM: S3C24XX: modify s3c2416 irq init to initialize all irqs ARM: S3C24XX: move s3c2416 irq init to common irq code ARM: S3C24XX: Modify s3c_irq_wake to use the hwirq property ARM: S3C24XX: Move irq syscore-ops to irq-pm clocksource: always define CLOCKSOURCE_OF_DECLARE ...

2013-02-05ARM: imx: support DEBUG_LL uart port selection for all i.MX SoCsShawn Guo
Extend imx6q DEBUG_LL uart port selection support to cover all i.MX SoCs. The 'range' of the Kconfig option gets dropped, as users looking at the option must know the uart number on his board. The bottom line is that the build system will report an error if an invalid port number is picked for given SoC. The header arch/arm/include/debug/imx-uart.h is created to accommodate all the uart base addresses. And the header will also be used for other low-level debug facility later.

2013-02-05ARM: imx: use separated debug uart symbol for imx31 and imx35Shawn Guo
It's improper to use combined symbol DEBUG_IMX31_IMX35_UART for imx31 and imx35, because imx31 has 5 UARTs while imx35 only has 3. So later when we add UART port selection for DEBUG_IMX31_IMX35_UART, we will have problem. Use separated Kconfig options for imx31 and imx35 debug uart selection.
