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)
