Merge branch 'clockevents/4.8' of http://git.linaro.org/people/daniel.lezcano/linux into timers/core
Pull the clockevents/clocksource tree from Daniel Lezcano: - Convert the clocksource-probe init functions to return a value in order to prepare the consolidation of the drivers using the DT. It is a big patchset but went through 01.org (kbuild bot), linux next and kernel-ci (continuous integration) (Daniel Lezcano) - Fix a bad error handling by returning the right value for cadence_ttc (Christophe Jaillet) - Fix typo in the Kconfig for the Samsung pwm (Alexandre Belloni) - Change functions to static for armada-370-xp and digicolor (Ben Dooks) - Add support for the rk3399 SoC timer by adding bindings and a slight change in the base address. Take the opportunity to add the DYNIRQ flag (Huang Tao) - Fix endian accessors for the Samsung pwm timer (Matthew Leach) - Add Oxford Semiconductor RPS Dual Timer driver (Neil Armstrong) - Add a kernel parameter to swich on/off the event stream feature of the arch arm timer (Will Deacon)
