2014-01-13sched_clock: Make ARM's sched_clock generic for all architecturesStephen Boyd
Nothing about the sched_clock implementation in the ARM port is specific to the architecture. Generalize the code so that other architectures can use it by selecting GENERIC_SCHED_CLOCK.

2013-07-28ARM: S3C24XX: Add missing clkdev entries for s3c2440 UARTSylwester Nawrocki
commit d817468c4b2892b9468e2a0c92116e38a3a61370 upstream. This patch restores serial port operation which has been broken since commit 60e93575476f ("serial: samsung: enable clock before clearing pending interrupts during init") That commit only uncovered the real issue which was missing clkdev entries for the "uart" clocks on S3C2440. It went unnoticed so far because return value of clk API calls were not being checked at all in the samsung serial port driver. This patch should be backported to at least 3.10 stable kernel, since the serial port has not been working on s3c2440 since 3.10-rc5.

2013-06-07ARM: EXYNOS: uncompress - print debug messages if DEBUG_LL is definedTushar Behera
Printing low-level debug messages make an assumption that the specified UART port has been preconfigured by the bootloader. Incorrectly specified UART port results in system getting stalled while printing the message "Uncompressing Linux... done, booting the kernel" This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since the UART port might different for different board, it is not possible to specify it correctly for every board that use a common defconfig file. Calling this print subroutine only when DEBUG_LL fixes the problem. By disabling DEBUG_LL in default config file, we would be able to boot multiple boards with different default UART ports. With this current approach, we miss the print "Uncompressing Linux... done, booting the kernel." when DEBUG_LL is not defined.

As a result, it should become really easy to add full multiplatform exynos support in 3.11, although we don't yet enable it for 3.10. The changes were not included in the earlier multiplatform series in order to avoid clashes with the other Exynos updates.

This series from Tomasz Figa restores support for the pwm clocksource in Exynos, which was broken during the conversion of the platform to the common clk framework.

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 ...

It has no users anymore and was in the way for other cleanups. attach_adapter() is sadly still there since there are users waiting to be converted. - the core gained a bus recovery infrastructure. I2C defines a way to recover if the data line is stalled.

2013-04-26Revert "ARM: exynos: enable multiplatform support"Olof Johansson
This reverts commit bd51de53e1be9896d815bbea30560262216d4616. Turns out that multiplatform breaks some uses cases, such as when you have an existing defconfig, since it adds the new EXYNOS_SINGLE config option as a dependecy. As a result, nearly all exynos config options will be disabled by default. Reverting instead of rebasing since this branch is pulled in as a dependency elsewhere.

2013-04-19ARM: exynos: enable multiplatform supportArnd Bergmann
This makes it possible to enable the exynos platform as part of a multiplatform kernel, in addition to keeping the single-platform exynos support. The multiplatform variant has a number of limitations at the moment: * It only supports DT-enabled machines. This is not a problem in the long run, as non-DT machines for exynos are going away. The main problem here is that the gpio code and the exynos_eint irqchip are not multiplatform capable but still required for ATAGS based boot. * The watchdog driver is still missing a conversion. * sparsemem and memory_holes are currently not supported in multiplatform. The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled for now, as dependent patches are still pending in other subsystem trees. We will enable it once everything comes together.

2013-04-12spi: s3c64xx: move to generic dmaengine APIArnd Bergmann
The spi-s3c64xx uses a Samsung proprietary interface for talking to the DMA engine, which does not work with multiplatform kernels. This version of the patch leaves the old code in place, behind an #ifdef. This can be removed in the future, after the s3c64xx platform start supporting the regular dmaengine interface. An earlier version of this patch was tested successfully on exynos5250 by Padma Venkat. The conversion was rather mechanical, since the samsung interface is just a shallow wrapper around the dmaengine interface. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2013-04-11tty: serial/samsung: make register definitions globalArnd Bergmann
The registers for the Samsung S3C serial port are currently defined in the platform specific arch/arm/plat-samsung/include/plat/regs-serial.h file, which is not visible to multiplatform capable drivers. Unfortunately, it is not possible to move the file into a more local place as we should normally try to, because the same registers may be used in one of four places: * In the driver itself * In platform-independent ARM code for early debug output * In platform_data definitions * In the Samsung platform power management code I have also found no way to logically split out a platform_data file, other than possibly move everything into include/linux/platform_data, which also felt wrong. The only part of this file that makes sense to keep specific to the s3c24xx platform are the virtual and physical addresses defined here, which are needed in no other location.
