Pull timer updates from Thomas Gleixner: "Updates for timekeeping, timers and related drivers: Core code: - Cure a couple of correctness issues in the posix CPU timer code to prevent that the tick dependency for NOHZ full is kept alive for no reason. - Avoid expensive double reprogramming of the clockevent device in hrtimer_start_range_ns(). - Avoid pointless SMP function calls when the clock was set to avoid disturbing CPUs which do not have any affected timers queued. - Make the clocksource watchdog test work correctly when CONFIG_HZ is less than 100. Drivers: - Prefer the ARM architected timer over the Exynos timer which is way more expensive to access. - Add device tree bindings for new Ingenic SoCs - The usual improvements and cleanups all over the place" * tag 'timers-core-2021-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (29 commits) clocksource: Make clocksource watchdog test safe for slow-HZ systems dt-bindings: timer: Add ABIs for new Ingenic SoCs clocksource/drivers/fttmr010: Pass around less pointers clocksource/drivers/mediatek: Optimize systimer irq clear flow on shutdown clocksource/drivers/ingenic: Use bitfield macro helpers clocksource/drivers/sh_cmt: Fix wrong setting if don't request IRQ for clock source channel dt-bindings: timer: convert rockchip,rk-timer.txt to YAML clocksource/drivers/exynos_mct: Mark MCT device as CLOCK_EVT_FEAT_PERCPU clocksource/drivers/exynos_mct: Prioritise Arm arch timer on arm64 hrtimer: Unbreak hrtimer_force_reprogram() hrtimer: Use raw_cpu_ptr() in clock_was_set() hrtimer: Avoid more SMP function calls in clock_was_set() hrtimer: Avoid unnecessary SMP function calls in clock_was_set() hrtimer: Add bases argument to clock_was_set() time/timekeeping: Avoid invoking clock_was_set() twice timekeeping: Distangle resume and clock-was-set events timerfd: Provide timerfd_resume() hrtimer: Force clock_was_set() handling for the HIGHRES=n, NOHZ=y case hrtimer: Ensure timerfd notification for HIGHRES=n hrtimer: Consolidate reprogramming code ...
