Merge branches 'clockevents/4.4-fixes' and 'clockevents/4.5-fixes' of http://git.linaro.org/people/daniel.lezcano/linux into timers/urgent

Pull in fixes from Daniel Lezcano:

 - Fix the vt8500 timer leading to a system lock up when dealing with too
   small delta (Roman Volkov)

 - Select the CLKSRC_MMIO when the fsl_ftm_timer is enabled with COMPILE_TEST
   (Daniel Lezcano)

 - Prevent to compile timers using the 'iomem' API when the architecture has
   not HAS_IOMEM set (Richard Weinberger)

Known issues & workaround

-------------------------



Some of the device drivers used on keystone are re-used from that from

DaVinci and other TI SoCs. These device drivers may use clock APIs directly.

Some of the keystone specific drivers such as netcp uses run time power

management API instead to enable clock. As this API has limitations on

keystone, following workaround is needed to boot Linux.



   Add 'clk_ignore_unused' to the bootargs env variable in u-boot. Otherwise

   clock frameworks will try to disable clocks that are unused and disable

   the hardware. This is because netcp related power domain and clock

   domains are enabled in u-boot as run time power management API currently

   doesn't enable clocks for netcp due to a limitation. This workaround is

   expected to be removed in the future when proper API support becomes

   available. Until then, this work around is needed.
