Merge branch 'fortglx/4.15/time' of https://git.linaro.org/people/john.stultz/linux into timers/core
Pull timekeeping updates from John Stultz: - More y2038 work from Arnd Bergmann - A new mechanism to allow RTC drivers to specify the resolution of the RTC so the suspend/resume code can make informed decisions whether to inject the suspended time or not in case of fast suspend/resume cycles.
