Kevin Hilman dd89dd98cb ARM: OMAP: TimerMPU: Remove MPU-timer based sched_clock()
Remove MPU-timer based sched_clock() in favor of the common one based
on 32k sync timer which works across all OMAP1/2/3 platforms.

Using 32k based one also gives a valid sched_clock() very early in the
boot process.

Kevin Hilman caa97963a5 ARM: OMAP: TimerMPU: Remove unused cycles-to-nsec conversions
These are no longer used and similar conversions are provided
by the clocksource/clockevent code.

Kevin Hilman 06cad098d2 ARM: OMAP: Fix clockevent support for hrtimers
One-shot mode was broken in MPU-timer support for OMAP1 due to a typo.

Also, ensure timer is stopped before changing the auto-reload flag.
The TRM says changing the AR flag when timer is running is undefined.

Also set GENERIC_CLOCKEVENTS for all omaps.

Thomas Gleixner 18de5bc4c1 clockevents: fix resume logic
We need to make sure, that the clockevent devices are resumed, before
the tick is resumed. The current resume logic does not guarantee this.

Add CLOCK_EVT_MODE_RESUME and call the set mode functions of the clock
event devices before resuming the tick / oneshot functionality.

Fixup the existing users.

Thanks to Nigel Cunningham for tracking down a long standing thinko,
which affected the jinxed VAIO.

Untested, but this should fix up the bulk of the totally mechanical

Thomas Gleixner 52e405eaa9 [PATCH] ARM: fixup irqflags breakage after ARM genirq merge
The irgflags consolidation did conflict with the ARM to generic IRQ
conversion and was not applied for ARM. Fix it up.
