MFGPT: move clocksource menu

2010-03-06T19:26:28+00:00

Move the CS5535 MFGPT hrtimer kconfig option to be with the other MFGPT
options.  This makes it easier to find and also removes it from the main
"Device Drivers" menu, where it should not have been.

clocksource: Fix up a registration/IRQ race in the sh drivers.

2010-02-25T07:37:46+00:00

All of the SH clocksource drivers follow the scheme that the IRQ is setup
prior to registering the clockevent. The interrupt handler in the
clockevent cases looks to the event handler function pointer being filled
in by the registration code, permitting us to get in to situations where
asserted IRQs step in to the handler before registration has had a chance
to complete and hitting a NULL pointer deref.

In practice this is not an issue for most platforms, but some of them
with fairly special loaders (or that are chain-loading from another
kernel) may enter in to this situation. This fixes up the oops reported
by Rafael on hp6xx.

geode-mfgpt: restore previous behavior for selecting IRQ

geode-mfgpt: restore previous behavior for selecting IRQ

The MFGPT IRQ used to be, in order of decreasing priority,
 * IRQ supplied by the user as a boot-time parameter,
 * IRQ previously set by the BIOS or another driver,
 * default IRQ given at compile time.

Return to this behavior, which got broken when splitting the
MFGPT/clocksource driver for 2.6.33-rc1.

clocksource: start CMT at clocksource resume

2010-02-05T13:54:10+00:00

Add code to start the CMT timer on clocksource resume.  While at it handle
the suspend case as well.  Remove the platform device specific suspend
calls.

This makes sure the timer is started during sysdev_resume().  Without this
patch the clocksource may be read as suspended, this after sysdev resume
but before platform device resume.

cs5535: add a generic clock event MFGPT driver

2009-12-15T16:53:28+00:00

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.

sh: CMT suspend/resume

2009-08-15T03:58:45+00:00

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.

clocksource: sh_tmu: Make undefined TCOR behaviour less undefined.

2009-06-24T12:08:11+00:00

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.
