This patchset adds support for memory mapped architected timers. We don't have any other global broadcast timer in our system, so we use the mmio timer during low power modes. The first patch is the binding. The next two patches lay some groundwork so that the last patch is simpler. The final patch adds support for mmio timers. Patches are based on a recent patch from Mark that removes the physical count reading (clocksource: arch_timer: use virtual counter, message id <1364404312-4427-4-git-send-email-mark.rutland@xxxxxxx>). Updates since v1: * Assigned counter reading function and commented why for arm64 * Updated DT binding to replace frame-id with frame-number and use status property Stephen Boyd (4): Documentation: Add memory mapped ARM architected timer binding ARM: arch_timers: Pass clock event to set_mode callback clocksource: arch_timer: Push the read/write wrappers deeper clocksource: arch_timer: Add support for memory mapped timers .../devicetree/bindings/arm/arch_timer.txt | 59 ++- arch/arm/include/asm/arch_timer.h | 5 +- arch/arm64/include/asm/arch_timer.h | 4 +- drivers/clocksource/arm_arch_timer.c | 455 +++++++++++++++++---- include/clocksource/arm_arch_timer.h | 4 +- 5 files changed, 449 insertions(+), 78 deletions(-) -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, hosted by The Linux Foundation -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
