The event streams can be used to impose a timeout on a wfe, to safeguard against any programming error in case an expected event is not generated or even to implement wfe-based timeouts for userspace locking implementations. Some files fall under the arm maintainers' umbrella but those changes have been reviewed and acked by the relevant people (Catalin Marinas and Olof Johansson). - Boris Brezillon improved the tcb_clksrc driver by removing a deprecated flag, checking return code values and using functions from the common clock framework. Thanks ! -- Daniel The following changes since commit 68e90740284c69292881cd38c7ece6f09a18a58f: Merge branch 'clockevents/3.13' of git://git.linaro.org/people/dlezcano/linux into timers/core (2013-10-03 07:57:02 +0200) are available in the git repository at: git://git.linaro.org/people/dlezcano/linux.git clockevents/3.13 for you to fetch changes up to f51380a75652a4600b34ce384c4ff89ce0a15132: clocksource: tcb_clksrc: Remove IRQF_DISABLED (2013-10-03 16:28:40 +0200) ---------------------------------------------------------------- Boris BREZILLON (3): clocksource: tcb_clksrc: Replace clk_enable/disable with clk_prepare_enable/disable_unprepare clocksource: tcb_clksrc: Improve driver robustness clocksource: tcb_clksrc: Remove IRQF_DISABLED Daniel Lezcano (1): Merge branch 'timer_evtstrm' of git://linux-arm.org/linux-skn into clockevents/3.13 Sudeep KarkadaNagesha (4): ARM/ARM64: arch_timer: add macros for bits in control register ARM: arch_timer: add support to configure and enable event stream ARM64: arch_timer: add support to configure and enable event stream drivers: clocksource: add CPU PM notifier for ARM architected timer Will Deacon (1): drivers: clocksource: add support for ARM architected timer event stream arch/arm/include/asm/arch_timer.h | 36 +++++++++++++++++--- arch/arm/include/uapi/asm/hwcap.h | 1 + arch/arm/kernel/setup.c | 1 + arch/arm64/include/asm/arch_timer.h | 42 +++++++++++++++++++---- arch/arm64/include/asm/hwcap.h | 11 +++--- arch/arm64/include/uapi/asm/hwcap.h | 1 + arch/arm64/kernel/setup.c | 11 ++++++ drivers/clocksource/Kconfig | 15 +++++++++ drivers/clocksource/arm_arch_timer.c | 49 +++++++++++++++++++++++++++ drivers/clocksource/tcb_clksrc.c | 61 ++++++++++++++++++++++++++++------ include/clocksource/arm_arch_timer.h | 10 ++++++ 11 files changed, 211 insertions(+), 27 deletions(-) -- Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog
