linux/drivers/clocksource, branch v2.6.32

sh: CMT suspend/resume

2009-08-15T03:58:45Z

This patch updates the SuperH CMT driver with suspend and resume callbacks for the suspend-to-ram case. This patch stops the CMT channel at suspend time to avoid unwanted wake up events. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

clocksource: sh_tmu: Make undefined TCOR behaviour less undefined.

2009-06-24T12:08:11Z

Avoid undocumented vague TMU behavior when zero value is set to TCOR. This primarily fixes up issues encountered under qemu with a zero-length period, while the hardware itself is fairly ambivalent one way or the other.

sh: turn off irqs when disabling CMT/TMU timers

2009-06-17T06:39:56Z

Modify the CMT and TMU drivers to disable interrupts when disabling the timer. Only using start/stop bits is not enough. This fixes a bootup hang on Migo-R when the CMT is replaced by TMU for clockevents but the CMT keeps on delivering irqs even though the timer start bit is off.

time: move PIT_TICK_RATE to linux/timex.h

2009-06-17T02:47:27Z

PIT_TICK_RATE is currently defined in four architectures, but in three different places. While linux/timex.h is not the perfect place for it, it is still a reasonable replacement for those drivers that traditionally use asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency. Note that for Alpha, the actual value changed from 1193182UL to 1193180UL. This is unlikely to make a difference, and probably can only improve accuracy. There was a discussion on the correct value of CLOCK_TICK_RATE a few years ago, after which every existing instance was getting changed to 1193182. According to the specification, it should be 1193181.818181...

clocksource: Drop unused irqaction.mask from SH drivers.

2009-06-14T12:18:24Z

The irqaction.mask is legacy code that is wholly unused and going away, so simply drop its use in the SH drivers completely. Fixes up build failures in -next. Signed-off-by: Paul Mundt

clocksource: sh_mtu2/cmt_register() should be static.

2009-05-03T09:05:42Z

Neither of these need to be exported, so just make them static. Signed-off-by: Paul Mundt

sh: Consolidate MTU2/CMT/TMU timer platform data.

2009-05-03T08:57:17Z

All of the SH timers use a roughly identical structure for platform data, which presently is broken out for each block. Consolidate all of these definitions, as there is no reason for them to be broken out in the first place. Signed-off-by: Paul Mundt

clocksource: SuperH TMU Timer driver

2009-05-03T08:41:15Z

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 Signed-off-by: Paul Mundt

clocksource: SuperH MTU2 Timer driver

2009-05-03T08:36:02Z

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.
