Ingo Molnar 1b3f828760 Merge branch 'clockevents/3.14' of git://git.linaro.org/people/daniel.lezcano/linux into timers/core
Pull clocksource/clockevent updates from Daniel Lezcano:

  * Axel Lin removed an unused structure defining the ids for the
    bcm kona driver.

  * Ezequiel Garcia enabled the timer divider only when the 25MHz
    timer is not used for the armada 370 XP.

  * Jingoo Han removed a pointless platform data initialization for
    the sh_mtu and sh_mtu2.

  * Laurent Pinchart added the clk_prepare/clk_unprepare for sh_cmt.

  * Linus Walleij added a useful warning in clk_of when no clocks
    are found while the old behavior was to silently hang at boot time.

  * Maxime Ripard added the high speed timer drivers for the
    Allwinner SoCs (A10, A13, A20). He increased the rating, shared the
    irq across all available cpus and fixed the clockevent's irq
    initialization for the sun4i.

  * Michael Opdenacker removed the usage of the IRQF_DISABLED for the
    all the timers driver located in drivers/clocksource.

  * Stephen Boyd switched to sched_clock_register for the
    arm_global_timer, cadence_ttc, sun4i and orion timers.

bool "Support for ARM architected timer event stream generation"

help
This option enables support for event stream generation based on
the ARM architected timer. It is used for waking up CPUs executing
the wfe instruction at a frequency represented as a power-of-2
divisor of the clock rate.
The main use of the event stream is wfe-based timeouts of userspace
locking implementations. It might also be useful for imposing timeout
on wfe to safeguard against any programming errors in case an expected
event is not generated.
This must be disabled for hardware validation purposes to detect any
hardware anomalies of missing events.
