Thanks to Jarkko Nikula for some comments on the sscanf() warnings.
It seems that the kernel sscanf() ignores the field width anyway for the
%d format, so those changes have been dropped from this second version.

Thanks to Daniel Marjamäki <daniel.marjamaki@gmail.com> for pointing
out that a variable was unnecessarily marked static in the
board-omap3evm.c change.

Since omap_dm_timer_write_reg/__omap_dm_timer_write is now modified
to use timer->func_base OCP_CFG should not use this wrapper anymore.
Instead use __raw_writel() directly and use timer->io_base instead
to write to OCP_CFG.

The timer->sys_stat is valid only if timer->revision is 1. In the
context restore function make this correction.

Save the contexts and loss count when timer is stopped.
Also, disable the clock. Else, clock usecount would become imbalanced.

The kernel timer queue is being run currently from a GP timer running in a one
shot mode, which works in a way that when it expires, it will also stop.
Usually during this situation, the interrupt handler will ack the interrupt,
load a new value to the timer and start it again. During suspend, the
situation is slightly different, as we disable interrupts just before
timekeeping is suspended, which leaves a small window where the timer can
expire before it is stopped, and will leave the interrupt flag pending.
This pending interrupt will prevent ARM sleep entry, thus now we ack it always
when we are attempting to stop a timer.

This patch fixes the compiler warning "assignment from incompatible
pointer type"  in dmtimer.c and removes the tye casts. These warnings
were suppressed by type catsing.

The proposed fix was suggested by Russell King <rmk+kernel@arm.linux.org.uk>

Add a function omap2_gp_clockevent_set_gptimer() for board-*.c files
to use in .init_irq functions to configure the system tick GPTIMER.
Practical choices at this point are GPTIMER1 or GPTIMER12.  Both of
these timers are in the WKUP powerdomain, and so are unaffected by
chip power management.  GPTIMER1 can use sys_clk as a source, for
applications where a high-resolution timer is more important than
power management.  GPTIMER12 has the special property that it has the
secure 32kHz oscillator as its source clock, which may be less prone
to glitches than the off-chip 32kHz oscillator.  But on HS devices, it
may not be available for Linux use.

It appears that most boards are fine with GPTIMER1, but BeagleBoard
should use GPTIMER12 when using a 32KiHz timer source, due to hardware bugs
in revisions B4 and below.  Modify board-omap3beagle.c to use GPTIMER12.

This patch originally used a Kbuild config option to select the GPTIMER,
but was changed to allow this to be specified in board-*.c files, per
Tony's request.

Kalle Vallo <kalle.valo@nokia.com> found a bug in an earlier version of
this patch - thanks Kalle.

Tested on Beagle rev B4 ES2.1, with and without CONFIG_OMAP_32K_TIMER, and
3430SDP.

All GP timers on OMAP2/3 can generate wakeup events.  The wakeup status is

The GPTIMER TLDR register does not need to be written if the GPTIMER
is not in autoreload mode.  This is the usual case for dynamic tick-enabled
kernels.

Simulation data indicate that skipping the read that occurs as part of
the write should save at least 300-320 ns for each GPTIMER1 timer
reprogram.  (This assumes L4-Wakeup is at 19MHz and GPTIMER write
posting is enabled.)  Skipping the write itself probably won't have
much impact since it should be posted on the OCP interconnect.

Tested on 2430SDP and 3430SDP.

omap_dm_timer_write_reg() already waits for pending writes to complete,
so the extra wait in omap_dm_timer_set_load() is superfluous.

OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies
for use with __raw_{read|write}* for accessing registers.  Therefore,
these macros should return (void __iomem *) cookies, not integer values.

Doing this improves typechecking, and means we can find those places
where, eg, DMA controllers are incorrectly given virtual addresses to
DMA to, or physical addresses are thrown through a virtual to physical
address translation.
