The following commit has been merged into the timers/core branch of tip: Commit-ID: 88183788eacb782eb6e1295f1934fb9531b503d6 Gitweb: https://git.kernel.org/tip/88183788eacb782eb6e1295f1934fb9531b503d6 Author: Will Deacon <will@xxxxxxxxxx> AuthorDate: Tue, 08 Jun 2021 16:43:41 +01:00 Committer: Daniel Lezcano <daniel.lezcano@xxxxxxxxxx> CommitterDate: Fri, 13 Aug 2021 09:24:22 +02:00 clocksource/drivers/exynos_mct: Mark MCT device as CLOCK_EVT_FEAT_PERCPU The "mct_tick" is a per-cpu clockevents device. Set the CLOCK_EVT_FEAT_PERCPU feature to prevent e.g. mct_tick0 being unsafely designated as the global broadcast timer and instead treat the device as a per-cpu wakeup timer.
