metag: Time keeping

2013-03-02T20:09:22Z

Add time keeping code for metag. Meta hardware threads have 2 timers. The background timer (TXTIMER) is used as a free-running time base, and the interrupt timer (TXTIMERI) is used for the timer interrupt. Both counters traditionally count at approximately 1MHz.

Pull ARM SoC mvebu platform changes from Olof Johansson: "This series contains changes for the Marvell EBU platforms (mvebu, orion, kirkwood, dove) that were not part of the first set of pull requests because of dependencies on the MMC tree, and being submitted a little late. Notable changes are: - More devices get moved out of board files into device tree descriptions. The remaining devices listed in there have patches that will get sent for 3.10, after which we can remove a lot of the board files entirely. We are doing the pinctrl and mmc drivers here, ethernet and PCI still remain. - SMP support for mvebu is improved with support for the local interrupt controller. - The Guruplug board file gets replaced with a DT description. Unfortunately, the dependency on the MMC tree turned out to be a much larger problem than expected, when the MMC maintainer rebased the patches in his tree that all of the patches in this branch are based on, which caused merge conflicts between the new and old versions of those patches. To work around the merge conflicts, this branch rebases all patches on top of the respective MMC patches that did get merged into 3.9. The patches are all identical to the versions that were part of linux-next, but have a new commit date." * tag 'late-mvebu-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (90 commits) arm: mvebu: enable the SD card slot on Armada 370 Reference Design board ARM: kirkwood: topkick: init mvsdio via DT ARM: kirkwood: nsa310: convert to pinctrl ARM: Kirkwood: topkick: Enable i2c bus.

clocksource: time-armada-370-xp: add local timer support

2013-02-28T17:57:07Z

On the SOCs Armada 370 and Armada XP, each CPU comes with two private timers. This patch use the timer 0 of each CPU as local timer for the clockevent if CONFIG_LOCAL_TIMER is selected. In the other case, use only the private Timer 0 of CPU 0. Signed-off-by: Gregory CLEMENT Signed-off-by: Jason Cooper

Pull ARM virtualization changes: "This contains parts of the ARM KVM support that have dependencies on other patches merged through the arm-soc tree. In combination with patches coming through Russell's tree, this will finally add full support for the kernel based virtual machine on ARM, which has been awaited for some time now. Further, we now have a separate platform for virtual machines and qemu booting that is used by both Xen and KVM, separating these from the Versatile Express reference implementation. Obviously, this new platform is multiplatform capable so it can be combined with existing machines in the same kernel." * tag 'virt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (38 commits) ARM: arch_timer: include linux/errno.h arm: arch_timer: add missing inline in stub function ARM: KVM: arch_timers: Wire the init code and config option ARM: KVM: arch_timers: Add timer world switch ARM: KVM: arch_timers: Add guest timer core support ARM: KVM: Add VGIC configuration option ARM: KVM: VGIC initialisation code ARM: KVM: VGIC control interface world switch ARM: KVM: VGIC interrupt injection ARM: KVM: vgic: retire queued, disabled interrupts ARM: KVM: VGIC virtual CPU interface management ARM: KVM: VGIC distributor handling ARM: KVM: VGIC accept vcpu and dist base addresses from user space ARM: KVM: Initial VGIC infrastructure code ARM: KVM: Keep track of currently running vcpus KVM: ARM: Introduce KVM_ARM_SET_DEVICE_ADDR ioctl ARM: gic: add __ASSEMBLY__ guard to C definitions ARM: gic: define GICH offsets for VGIC support ARM: gic: add missing distributor defintions ARM: mach-virt: fixup machine descriptor after removal of sys_timer ...

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 ...
