Merge branch 'clockevents/4.13' of https://git.linaro.org/people/daniel.lezcano/linux into timers/core

Pull clockevent changes from Daniel Lezcano:

 - Factored out moxart, aspeed, cortina drivers into a generic timer fttrm010.
   Take the opportunity to add the delay timer (Linus Walleij)

 - Saved / restored tcb atmel context at suspend/resume (Alexandre Belloni)

 - Added ast2500 compatible string and fixed aspeed2500 initialization (Daniel
   Lezcano)

 - Added clock names property for aspeed (Andrew Jeffery)

 - Renamed clocksource_of to timer_of (Daniel Lezcano)

 - Added a common timer init routine (Daniel Lezcano)
