Merge tag 'v3.12-pwm-cleanup-for-olof' of git://github.com/tom3q/linux into next/cleanup
From Tomasz Figa: Here is the Samsung PWM cleanup series. Particular patches of the series involve following modifications: - fixing up few things in samsung_pwm_timer clocksource driver, - moving remaining Samsung platforms to the new clocksource driver, - removing old clocksource driver, - adding new multiplatform- and DT-aware PWM driver, - moving all Samsung platforms to use the new PWM driver, - removing old PWM driver, - removing all PWM-related code that is not used anymore. * tag 'v3.12-pwm-cleanup-for-olof' of git://github.com/tom3q/linux: (684 commits) ARM: SAMSUNG: Remove plat/regs-timer.h header ARM: SAMSUNG: Remove remaining uses of plat/regs-timer.h header ARM: SAMSUNG: Remove pwm-clock infrastructure ARM: SAMSUNG: Remove old PWM timer platform devices pwm: Remove superseded pwm-samsung-legacy driver ARM: SAMSUNG: Modify board files to use new PWM platform device ARM: SAMSUNG: Rework private data handling in dev-backlight pwm: Add new pwm-samsung driver pwm: samsung: Rename to pwm-samsung-legacy ARM: SAMSUNG: Remove unused PWM timer IRQ chip code ARM: SAMSUNG: Remove old samsung-time driver ARM: SAMSUNG: Move all platforms to new clocksource driver ARM: SAMSUNG: Set PWM platform data ARM: SAMSUNG: Add new PWM platform device ARM: SAMSUNG: Unify base address definitions of timer block clocksource: samsung_pwm_timer: Handle suspend/resume correctly clocksource: samsung_pwm_timer: Do not use clocksource_mmio clocksource: samsung_pwm_timer: Cache clocksource register address clocksource: samsung_pwm_timer: Correct definition of AUTORELOAD bit clocksource: samsung_pwm_timer: Do not request PWM mem region + v3.11-rc4 Conflicts: arch/arm/Kconfig.debug Signed-off-by: Olof Johansson <olof@lixom.net>
