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
