This series is an attempt to make the samsung-time clocksource driver ready for multiplatform kernels. It moves the driver to drivers/clocksource, cleans it up from uses of static platform-specific definitions, simplifies timer interrupt handling and adds Device Tree support. The samsung_pwm clocksource driver is made the master driver, which exposes a single function to the PWM driver to get required data. Only samsung-time driver is reworked to use the master driver at this time, since the PWM driver can be already considered broken at the moment and needs separate series of several patches to fix and clean it up, which I am already working on. Tested on Universal C210 board with Device Tree. Not tested without Device Tree, since it has been already broken before this series. Compile tested for other related SoCs. Changes since v4: (http://thread.gmane.org/gmane.linux.kernel.samsung-soc/17464) - Changed the design again - now clocksource driver is considered the master and exports a single function to get access to things like base address, hardware variant information, shared spinlock for register access synchronization and interrupt numbers - Renamed the clocksource driver to samsung_pwm - Cleaned up the code a bit more - Added clocksource_of_init support Changes since v3: (http://thread.gmane.org/gmane.linux.kernel.samsung-soc/16664/) - Changed the design to use common (master) driver for operations that can be done from both clocksource and PWM drivers (as suggested by Arnd Bergmann) - needed to properly synchronize access to PWM registers - Moved handling of PWM prescaler and divider to master driver Changes since v2: (http://thread.gmane.org/gmane.linux.kernel.samsung-soc/16158) - Addressed comments from Rob Herring and Mark Rutland - Removed unused register definitions - Replaced samsung,source-timer and samsung,event-timer properties with samsung,pwm-outputs property that defines which PWM channels are reserved for PWM outputs on particular platform - Split non-DT and DT initialization into two functions - Fixed a copy paste error Changes since v1: (http://thread.gmane.org/gmane.linux.kernel.samsung-soc/16005) - Addressed comments from Mark Rutland - Documented struct samsung_timer_variant - Dropped inactive mail addresses from CC Tomasz Figa (14): ARM: SAMSUNG: Move samsung-time to drivers/clocksource clocksource: samsung-pwm: Clean up platform header clocksource: samsung-pwm: Add infrastructure to share PWM hardware ARM: SAMSUNG: Unify base address definitions of timer block ARM: SAMSUNG: Add new PWM platform device ARM: SAMSUNG: Set PWM platform data clocksource: samsung-pwm: Use platform data to setup the clocksource clocksource: samsung-pwm: Synchronize register accesses clocksource: samsung-pwm: Move IRQ mask/ack handling to the driver ARM: SAMSUNG: Remove unused PWM timer IRQ chip code clocksource: samsung-pwm: Configure dividers directly clocksource: samsung-pwm: Do not use static mapping of registers clocksource: samsung-pwm: Drop unnecessary includes clocksource: samsung-pwm: Prepare for clocksource_of_init .../devicetree/bindings/pwm/pwm-samsung.txt | 43 ++ arch/arm/Kconfig | 1 - arch/arm/mach-exynos/common.c | 10 + arch/arm/mach-exynos/include/mach/irqs.h | 3 +- arch/arm/mach-exynos/include/mach/map.h | 1 + arch/arm/mach-s3c24xx/common.c | 10 + arch/arm/mach-s3c24xx/include/mach/irqs.h | 6 + arch/arm/mach-s3c24xx/include/mach/map.h | 2 + arch/arm/mach-s3c64xx/common.c | 14 +- arch/arm/mach-s3c64xx/include/mach/irqs.h | 8 - arch/arm/mach-s3c64xx/include/mach/map.h | 1 + arch/arm/mach-s5p64x0/common.c | 10 + arch/arm/mach-s5p64x0/include/mach/irqs.h | 2 - arch/arm/mach-s5p64x0/include/mach/map.h | 1 + arch/arm/mach-s5pc100/common.c | 10 + arch/arm/mach-s5pc100/include/mach/irqs.h | 2 - arch/arm/mach-s5pc100/include/mach/map.h | 1 + arch/arm/mach-s5pv210/common.c | 10 + arch/arm/mach-s5pv210/include/mach/irqs.h | 2 - arch/arm/mach-s5pv210/include/mach/map.h | 1 + arch/arm/plat-samsung/Kconfig | 14 - arch/arm/plat-samsung/Makefile | 2 - arch/arm/plat-samsung/devs.c | 33 +- arch/arm/plat-samsung/include/plat/devs.h | 1 + arch/arm/plat-samsung/include/plat/irq-vic-timer.h | 13 - arch/arm/plat-samsung/include/plat/irqs.h | 9 - arch/arm/plat-samsung/include/plat/samsung-time.h | 38 +- arch/arm/plat-samsung/irq-vic-timer.c | 98 ---- arch/arm/plat-samsung/s5p-irq.c | 3 - arch/arm/plat-samsung/samsung-time.c | 394 ------------- drivers/clocksource/Kconfig | 7 + drivers/clocksource/Makefile | 1 + drivers/clocksource/samsung_pwm.c | 636 +++++++++++++++++++++ include/clocksource/samsung_pwm.h | 45 ++ 34 files changed, 849 insertions(+), 583 deletions(-) create mode 100644 Documentation/devicetree/bindings/pwm/pwm-samsung.txt delete mode 100644 arch/arm/plat-samsung/include/plat/irq-vic-timer.h delete mode 100644 arch/arm/plat-samsung/irq-vic-timer.c delete mode 100644 arch/arm/plat-samsung/samsung-time.c create mode 100644 drivers/clocksource/samsung_pwm.c create mode 100644 include/clocksource/samsung_pwm.h -- 1.8.1.5 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
