Merge branch 'exynos/pwm-clocksource' into late/multiplatform
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. The clocksource is only used in one board in the mainline kernel (universal_c210), and this makes it work for DT based probing as well as restoring the non-DT based case. * exynos/pwm-clocksource: ARM: dts: exynops4210: really add universal_c210 dts ARM: dts: exynos4210: Add basic dts file for universal_c210 board ARM: dts: exynos4: Add node for PWM device ARM: SAMSUNG: Do not register legacy timer interrupts on Exynos clocksource: samsung_pwm_timer: Work around rounding errors in clockevents core clocksource: samsung_pwm_timer: Correct programming of clock events clocksource: samsung_pwm_timer: Use proper clockevents max_delta clocksource: samsung_pwm_timer: Add support for non-DT platforms clocksource: samsung_pwm_timer: Drop unused samsung_pwm struct clocksource: samsung_pwm_timer: Keep all driver data in a structure clocksource: samsung_pwm_timer: Make PWM spinlock global clocksource: samsung_pwm_timer: Let platforms select the driver Documentation: Add device tree bindings for Samsung PWM timers clocksource: add samsung pwm timer driver Conflicts: arch/arm/boot/dts/Makefile arch/arm/mach-exynos/common.c drivers/clocksource/Kconfig drivers/clocksource/Makefile Signed-off-by: Arnd Bergmann <arnd@arndb.de>

+ This is a new clocksource driver for the PWM timer found in
+ Samsung S3C, S5P and Exynos SoCs, replacing an earlier driver
+ for all devicetree enabled platforms. This driver will be
+ needed only on systems that do not have the Exynos MCT available.
