2012-05-25clocksource: em_sti: Emma Mobile STI driverMagnus Damm
The STI hardware is based on a single 48-bit 32kHz counter that together with two individual compare registers can generate interrupts. There are no timer operating modes selectable which means that the timer can not clear on match. This driver is providing clocksource support for the 48-bit counter. Clockevents are also supported using the same timer in oneshot mode.

2011-06-27clocksource: apb: Share APB timer code with other platformsJamie Iles
The APB timers are an IP block from Synopsys (DesignWare APB timers) and are also found in other systems including ARM SoC's. This patch adds functions for creating clock_event_devices and clocksources from APB timers but does not do the resource allocation. This is handled in a higher layer to allow the timers to be created from multiple methods such as platform_devices. Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: "H.

2011-05-23clocksource: add common mmio clocksourceRussell King
Add a generic mmio clocksource, covering both 32-bit and 16-bit register access sizes, for up or down counters. This can be used to easily create clocksources for simple counter-based implementations.

2009-12-15cs5535: add a generic clock event MFGPT driverAndres Salomon
This is based on the old code in arch/x86/kernel/mfgpt_32.c, but is modular and not Geode-specific. There's no reason why the clock event device needs to be registered so early at boot; the clockevent code is perfectly capable of dynamic switching.

2009-05-03clocksource: SuperH TMU Timer driverMagnus Damm
This patch adds a TMU driver for the SuperH architecture. The TMU driver is a platform driver with early platform support to allow using a TMU channel as clockevent or clocksource during system bootup or later. Clocksource or clockevent can be selected. Both periodic and oneshot clockevents are supported. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-03clocksource: SuperH MTU2 Timer driverMagnus Damm
This patch adds a MTU2 driver for the SuperH architecture. The MTU2 driver is a platform driver with early platform support to allow using a MTU2 channel as only clockevent during system bootup. Clocksource on sh2a is currently unsupported due to code generation issues with 64-bit math, so at this point only periodic clockevent support is in place.

2009-01-29sh: CMT clockevent platform driverMagnus Damm
SuperH CMT clockevent driver. Both 16-bit and 32-bit CMT versions are supported, but only 32-bit is tested. This driver contains support for both clockevents and clocksources, but no unregistration is supported at this point. Works fine as clock source and/or event in periodic or oneshot mode. Tested on sh7722 and sh7723, but should work with any cpu/architecture. This version is lacking clocksource and early platform driver support for now - this to minimize the amount of dependencies.

2008-03-04atmel_tc clocksource/clockevent codeDavid Brownell
Clocksource and clockevent device based on the Atmel TC blocks. The clockevent device handles both periodic and oneshot modes, so this enables NO_HZ and high res timers on some platforms that previously couldn't use those mechanisms. This works on both AVR32 and AT91 chips, given relevant patches for tclib support (always) and clockevents (or else this will only look like a higher precision clocksource). It's an updated and modularized version of an AT91-only patch that has circulated for some time now. Changes relative to the original patch: * Update to use new tclib API * Replace open-coded do-while loop using goto with a real do-while loop * Minor irq handler optimization: Load register base address from dev_id instead of a global variable. * Aggressively turn off clocks when the clockevent isn't being used * Include the clockevent code on AT91RM9200 as well. The rating is lower than the System Timer, so the clock will usually stay off. * Don't assume that the number of clocks is always equal to the number of irqs.

Implement the time sources for i386 (acpi_pm, cyclone, hpet, pit, and tsc). With this patch, the conversion of the i386 arch to the generic timekeeping code should be complete. The patch should be fairly straight forward, only adding the new clocksources.
