Subject: clocksource: SuperH TMU Timer driver

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.

Date: Sun, 3 May 2009 17:57:17 +0900
Subject: sh: Consolidate MTU2/CMT/TMU timer platform data.

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.

Subject: clocksource: Drop unused irqaction.mask from SH drivers.

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.

Subject: sh: turn off irqs when disabling CMT/TMU timers

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.
