Pull x86 timer updates from Thomas Gleixner: - Use the topology information of number of packages for making the decision about TSC trust instead of using the number of online nodes which is not reflecting the real topology. - Stop the PIT timer 0 when its not in use as to stop pointless emulation in the VMM. - Fix the PIT timer stop sequence for timer 0 so it truly stops both real hardware and buggy VMM emulations. * tag 'x86-timers-2024-09-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/tsc: Check for sockets instead of CPUs to make code match comment clockevents/drivers/i8253: Fix stop sequence for timer 0 x86/i8253: Disable PIT timer 0 when not in use x86/tsc: Use topology_max_packages() to get package number

Pull timer updates from Thomas Gleixner: "Core: - Overhaul of posix-timers in preparation of removing the workaround for periodic timers which have signal delivery ignored. - Remove the historical extra jiffie in msleep() msleep() adds an extra jiffie to the timeout value to ensure minimal sleep time. The timer wheel ensures minimal sleep time since the large rewrite to a non-cascading wheel, but the extra jiffie in msleep() remained unnoticed. Remove it. - Make the timer slack handling correct for realtime tasks. The procfs interface is inconsistent and does neither reflect reality nor conforms to the man page. Show the correct 0 slack for real time tasks and enforce it at the core level instead of having inconsistent individual checks in various timer setup functions. - The usual set of updates and enhancements all over the place. Drivers: - Allow the ACPI PM timer to be turned off during suspend - No new drivers - The usual updates and enhancements in various drivers" * tag 'timers-core-2024-09-16' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (43 commits) ntp: Make sure RTC is synchronized when time goes backwards treewide: Fix wrong singular form of jiffies in comments cpu: Use already existing usleep_range() timers: Rename next_expiry_recalc() to be unique platform/x86:intel/pmc: Fix comment for the pmc_core_acpi_pm_timer_suspend_resume function clocksource/drivers/jcore: Use request_percpu_irq() clocksource/drivers/cadence-ttc: Add missing clk_disable_unprepare in ttc_setup_clockevent clocksource/drivers/asm9260: Add missing clk_disable_unprepare in asm9260_timer_init clocksource/drivers/qcom: Add missing iounmap() on errors in msm_dt_timer_init() clocksource/drivers/ingenic: Use devm_clk_get_enabled() helpers platform/x86:intel/pmc: Enable the ACPI PM Timer to be turned off when suspended clocksource: acpi_pm: Add external callback for suspend/resume clocksource/drivers/arm_arch_timer: Using for_each_available_child_of_node_scoped() dt-bindings: timer: rockchip: Add rk3576 compatible timers: Annotate possible non critical data race of next_expiry timers: Remove historical extra jiffie for timeout in msleep() hrtimer: Use and report correct timerslack values for realtime tasks hrtimer: Annotate hrtimer_cpu_base_.*_expiry() for sparse. timers: Add sparse annotation for timer_sync_wait_running(). signal: Replace BUG_ON()s ...

Add the missing iounmap() when clock frequency fails to get read by the of_property_read_u32() call, or if the call to msm_timer_init() fails.

clocksource/drivers/ingenic: Use devm_clk_get_enabled() helpers

2024-09-06T12:49:20Z

The devm_clk_get_enabled() helpers: - call devm_clk_get() - call clk_prepare_enable() and register what is needed in order to call clk_disable_unprepare() when needed, as a managed resource. This simplifies the code and avoids the calls to clk_disable_unprepare(). Signed-off-by: Huan Yang Link: https://lore.kernel.org/r/20240820094603.103598-1-link@vivo.com Signed-off-by: Daniel Lezcano
