2013-05-27ARM: ux500: Provide supplies for AUX1, AUX2 and AUX3Lee Jones
This patch fixes a bug introduced in the v3.10 merge window. The AB8500 External Regulator driver has recently landed upstream, which registers each of the 3 external regulators located on the AB8500. If these regulators are marked as 'always on', there is a potential for power-loss. If they're not and are seemingly unused the Regulator subsystem will attempt to disable them to save power. This causes an issue for AUX1, AUX2 and AUX3 as they obtain their power from EXT3. So we're specifying that here to prevent EXT3 from being powered down.

2013-05-27ARM: ux500: Only configure wake-up reasons on ux500 based platformsLee Jones
Multiplatform calls all enabled platforms' initcalls. In the ux500_idle_init() initcall we call into the DBx500-PRCMU which in turn executes some ux500 specific register reads/writes. When running on some !ux500 platforms this ends up causing a kernel Oops. This patch ensures the PRCMU call is only invoked when running on ux500 based platforms.

2013-05-14ARM: ux500: Provide device enumeration number suffix for SMSC911xLee Jones
First Ethernet device has a ".0" appended onto the device name. Since on a non-DT boot the ethernet will be named "smsc911x.0" and since the clocks are not converted to device tree these names need to be matched when providing the name from auxdata.

2013-05-14ARM: ux500: Remove duplicated assignment of ab8500_platdataLee Jones
Since: "05ec260 mfd: db8500-prcmu: update resource passing", the AB8500's platform data 'ab8500_platdata' is passed directly as an attribute to 'db8500_prcmu_pdata', so there's no requirement to assign it a second time. In fact, it's only due to an ordering issue that the entire 'db8500_prcmu_pdata' data structure isn't completely over-written by the assignment in u8500_init_devices().

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver changes from Olof Johansson: "This is a rather large set of patches for device drivers that for one reason or another the subsystem maintainer preferred to get merged through the arm-soc tree. There are both new drivers as well as existing drivers that are getting converted from platform-specific code into standalone drivers using the appropriate subsystem specific interfaces. In particular, we can now have pinctrl, clk, clksource and irqchip drivers in one file per driver, without the need to call into platform specific interface, or to get called from platform specific code, as long as all information about the hardware is provided through a device tree. Most of the drivers we touch this time are for clocksource. Since now most of them are part of drivers/clocksource, I expect that we won't have to touch these again from arm-soc and can let the clocksource maintainers take care of these in the future. Another larger part of this series is specific to the exynos platform, which is seeing some significant effort in upstreaming and modernization of its device drivers this time around, which unfortunately is also the cause for the churn and a lot of the merge conflicts. There is one new subsystem that gets merged as part of this series: the reset controller interface, which is a very simple interface for taking devices on the SoC out of reset or back into reset. Patches to use this interface on i.MX follow later in this merge window, and we are going to have other platforms (at least tegra and sirf) get converted in 3.11. This will let us get rid of platform specific callbacks in a number of platform independent device drivers." * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (256 commits) irqchip: s3c24xx: add missing __init annotations ARM: dts: Disable the RTC by default on exynos5 clk: exynos5250: Fix parent clock for sclk_mmc{0,1,2,3} ARM: exynos: restore mach/regs-clock.h for exynos5 clocksource: exynos_mct: fix build error on non-DT pinctrl: vt8500: wmt: Fix checking return value of pinctrl_register() irqchip: vt8500: Convert arch-vt8500 to new irqchip infrastructure reset: NULL deref on allocation failure reset: Add reset controller API dt: describe base reset signal binding ARM: EXYNOS: Add arm-pmu DT binding for exynos421x ARM: EXYNOS: Add arm-pmu DT binding for exynos5250 ARM: EXYNOS: Enable PMUs for exynos4 irqchip: exynos-combiner: Correct combined IRQs for exynos4 irqchip: exynos-combiner: Add set_irq_affinity function for combiner_irq ARM: EXYNOS: fix compilation error introduced due to common clock migration clk: exynos5250: Fix divider values for sclk_mmc{0,1,2,3} clk: exynos4: export clocks required for fimc-is clk: samsung: Fix compilation error clk: tegra: fix enum tegra114_clk to match binding ...
2013-05-03ARM: ux500: always select ABX500_COREArnd Bergmann
We are probably selecting more drivers than we should in ux500, but cleaning up that logic for good can be left for another time. Most of these could be converted into silent options in the future, since they are always enabled on ux500 and never needed elsewhere. As a fixup for 3.10, let's at least select the dependencies for the other drivers we already select, to make it consistent. warning: (UX500_SOC_COMMON) selects AB8500_CORE which has unmet direct dependencies (HAS_IOMEM && GENERIC_HARDIRQS && ABX500_CORE && MFD_DB8500_PRCMU) Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>

The TWD and SCU configs are selected by default as long as MSM_SCORPIONMP is false and/or MCT is false. Implementing the logic this way certainly saves lines in the Kconfig but it precludes those machines which select MSM_SCORPIONMP or MCT from participating in the single zImage effort because when those machines are combined with other SMP capable machines the TWD and SCU are no longer selected by default. Push the select out to the machine entries so that we can compile these machines together and still select the appropriate configs.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers From Tony Lindgren <tony@atomide.com>: Clean-up for omap2+ timers from Jon Hunter <jon-hunter@ti.com>: This series consists mainly of clean-ups for clockevents and clocksource timers on OMAP2+ devices. The most significant change in functionality comes from the 5th patch which is changing the selection of the clocksource timer for OMAP3 and AM335x devices when gptimers are used for clocksource. Note that this series depends on 7185684 (ARM: OMAP: use consistent error checking) in RMK's tree and 960cba6 (ARM: OMAP5: timer: Update the clocksource name as per clock data) in omap-for-v3.10/fixes-non-critical. So this branch is based on a merge of 7185684 and omap-for-v3.10/fixes-non-critical to avoid non-trivial merge conflicts. * tag 'omap-for-v3.10/timer-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP4+: Fix sparse warning in system timers ARM: OMAP2+: Store ID of system timers in timer structure ARM: OMAP3: Update clocksource timer selection ARM: OMAP2+: Simplify system timers definitions ARM: OMAP2+: Simplify system timer clock definitions ARM: OMAP2+: Remove hard-coded test on timer ID ARM: OMAP2+: Display correct system timer name ARM: OMAP2+: fix typo "CONFIG_BRIDGE_DVFS" ARM: OMAP1: remove "config MACH_OMAP_HTCWIZARD" ARM: OMAP: dpll: enable bypass clock only when attempting dpll bypass ARM: OMAP2+: powerdomain: avoid testing whether an unsigned char is less than 0 ARM: OMAP2+: hwmod: Remove unused _HWMOD_WAKEUP_ENABLED flag ARM: OMAP2+: am335x: Change the wdt1 func clk src to per_32k clk ARM: OMAP2+: AM33xx: hwmod: Add missing sysc definition to wdt1 entry Signed-off-by: Arnd Bergmann <arnd@arndb.de>

If we try to build this file in a multiplatform configuration with ARMv6 enabled, gas complains about the dsb operation being undefined. Adding -march=armv7-a is safe because that code is only ever run on ux500, which is Cortex-A9. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-04-08ARM: ux500: make irqs.h local to platformArnd Bergmann
With the PRCMU out of the way, nothing outside of mach-ux500 uses mach/irqs.h any more, so we can make it a local header file, including the two sub-headers. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-04-08ARM: ux500: get rid of <mach/[hardware|db8500-regs].h>Linus Walleij
This removes <mach/hardware.h> and <mach/db8500-regs.h> from the Ux500, merging them into the local include "db8500-regs.h" in mach-ux500. There is some impact outside the ux500 machine, but most of it is dealt with in earlier patches. Contains portions of a clean-up patch from Arnd Bergmann.

2013-04-08staging: ste_rmi4: kill platform_data hackArnd Bergmann
There is only one instance of the platform data for synaptics_i2c_rmi4 in the mainline kernel, so there is no point of pretending its variable here. The only member that has a dependency on the platform is actually the interrupt number, and there is a field in the i2c_client structure that gets initialized from the board info, so we can trivially move the board_into into the platform without knowledge of the platform_data structure.

2013-04-08ARM: ux500: split out prcmu initializationArnd Bergmann
This untangles the final bits of the prcmu code from the platform code: * The IRQ_PRCMU_* definitions move from irqs-db8500.h into prcmu.c because they are only of local significance. * u8500_thsens_device goes into the prcmu, because it uses a PRCMU IRQ that the platform does not see. * IRQ_DB8500_AB8500 and IRQ_PRCMU_BASE go into the platform data because the PRCMU does not see it.

2013-04-08ARM: ux500: move PM-related PRCMU functions to machineLinus Walleij
We are trying to decompose and decentralize the code in the DB8500 PRCMU out into subdrivers. The code moved in this patch concerns a group of functions used for decoupling and recoupling the IRQs from the GIC. During sleep and idle the Ux500 system will transfer all IRQ handling to the PRCMU using these functions. Basically we are left with the two alternatives of code placement as: - arch/arm/mach-ux500/pm.c - this because the code is closely related to the GIC, and takes ownership of some of the registers from the PRCMU related to this PM functionality. - drivers/mfd/db8500-prcmu-pm.c - because the code is affecting stuff in the PRCMU register range. But then this code needs to remap and handle GIC registers. This patch implementation is taking the first approach. Currently the cpuidle driver is the only piece of code using this set of functions, but it will later also be used by the suspend/resume code which is currently under review. The header file is moved to: <linux/platform_data/arm-ux500-pm.h> The function prototypes need to be placed in a globally visible header since the CPUidle code is planned to move out to drivers/cpuidle.

2013-04-08mfd: db8500-prcmu: get base address from resourceLinus Walleij
We cannot use a global variable stored in <mach/hardware.h> to find the base address of the PRCMU. The real resource is already there from the board, so use this to look up the base address instead. Currently the patch is kept minimal so as not to interfere with other work being done on refactoring this driver, but at a later point the defines using (prcmu_base + 0xnnn) need to be replaced by pure offset defined for (0xnnn) and the base inlined with the readl()/writel() and similar codepaths.

2013-04-08mfd: prcmu: pass a base and size with the early initcallLinus Walleij
This patch will make an early remapping of the PRCMU, to be used when setting up the clocks, that will call down into parts of the PRCMU driver before it is probed. Going forward this will be removed like this: - The mailbox subsystem need to be merged. http://marc.info/?l=linux-kernel&m=136314559201983&w=2 - At this point the PRCMU clock code can be moved over to the ux500 clock driver in drivers/clk/ux500/* and maintained there in a decentralized manner. - This early initcall and PRCMU base parameters become part of the ux500_clk_init() call instead.
