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.
