Merge branch 'clockevents/fixes' of... 

Merge branch 'clockevents/fixes' of git://git.linaro.org/people/daniel.lezcano/linux

 into timers/urgent

Pull clockevents/clocksource fixes from Daniel Lezcano:

  * Axel Lin added a missing dependency on CLKSRC_MMIO in the Kconfig
    for the time-efm32

  * Dinh Nguyen fixed read_sched_clock to return the right value and
    added the clksrc-of missing definition for the dw_apb_timer

  * Ezequiel Garcia registered the sched clock after the counter,
    thus preventing time jump in the traces for the armada-370-xp

  * Marc Zyngier stopped the timer before enabling the irq in order
    to prevent it to be fired before the clockevent is registered for
    the sunxi

  * Thierry Reding removed a of_node_put in clksrc-of because the
    reference is not held
