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.

2013-03-27ARM: ux500: Enable the clock controlling Ethernet on SnowballLee Jones
This fixes a regression introduced by common clk enablement. On some u8500 based boards, the FMSC clock which is usually used for flash, is wired up to the SMSC911x Ethernet driver. However, the SMSC911x doesn't have common clk support yet, rendering it unusable. Prior to the introduction of common clk the FMSC clock was default on; however, common clk disables all clocks by default and insists drivers take responsibility to enable theirs. This fix enables the FMSC clock on Snowball, subsequently turning on the SMSC911x Ethernet chip. It will be removed when the driver is compatible with common clk.

2013-02-24ARM: cleanup: soc_device_register() error checkingRussell King
soc_device_register() never returns NULL, it only ever returns an error pointer or a valid pointer. Use the right function (IS_ERR()) to check this. soc_device_to_device() only ever returns &soc_dev->dev, and so can never return an error or NULL if the pointer passed into it was valid, so there's no point checking its return.

2013-02-21Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-socLinus Torvalds
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 ...

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull non-critical ARM SoC bug fixes from Arnd Bergmann: "Bug fixes that did not make it into v3.8, mostly because they were not considered important enough, and in some cases because bugs only show up in combination with other patches destined for 3.9. This includes a few larger patches for GPIO on the Marvell PXA platform and a lot of Samsung specific bug fixes, as well as a series from Arnd to fix older build warnings." * tag 'fixes-non-critical' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (54 commits) ARM: SPEAr13xx: Enable CONFIG_ARCH_HAS_CPUFREQ ARM: imx: MACH_MX31ADS_WM1133_EV1 needs REGULATOR_WM8350 scripts/sortextable: silence script output ARM: s3c: i2c: add platform_device forward declaration ARM: mvebu: allow selecting mvebu without Armada XP ARM: pick Versatile by default for !MMU ARM: integrator: fix build with INTEGRATOR_AP off ARM: integrator/versatile: fix NOMMU warnings ARM: sa1100: don't warn about mach/ide.h ARM: shmobile: fix defconfig warning on CONFIG_USB ARM: w90x900: fix legacy assembly syntax ARM: samsung: fix assembly syntax for new gas ARM: disable virt_to_bus/virt_to_bus almost everywhere ARM: dts: Correct pin configuration of SD 4 for exynos4x12-pinctrl ARM: SAMSUNG: Silence empty switch warning in fimc-core.h ARM: SAMSUNG: Silence empty switch warning in sdhci.h ARM: msm: proc_comm_boot_wait should not be __init arm: vt8500: Update MAINTAINERS entry for arch-vt8500 ARM: integrator: ensure ap_syscon_base is initialised when !CONFIG_MMU ARM: S5PV210: Fix early uart output in fifo mode ...
