- handling of boundary parameter values,
- hardware sharing with PWM clocksource driver,
- undefined state of PWM output after stopping PWM channel.

This series removes the currently-unused PRCM macros from
arch/arm/mach-omap2.
Basic test logs are available at:
http://www.pwsan.com/omap/testlogs/drop_unused_prcm_macros_v3.11-rc/20130721211401/
Once, years ago, we thought that it would be good to document the PRCM
register bits in the Linux codebase. Most folks in the broader
community did not have access to the same documentation, so we thought
that they might be able to use these bits to fix bugs and improve the
code.
We were also able to autogenerate most of these macros, so it was
thought that defining them in advance would reduce the risk of error,
inconsistencies, and merge conflicts caused when patch sets
incrementally defined them by hand.
Well, nice thoughts. But the first rationale was rendered partially
obsolete when TI started to release public TRM documentation PDFs at
some point in the OMAP3 timeframe. (Despite their weaknesses, TI's
public OMAP TRMs remain the most useful public documentation available
for any ARM Linux SoC -- at least to the extent of my knowledge.) And
then the current Linux development tropism towards
development-by-negative-diffstat obliterated the remainder of the
above two philosophies.
So, for the few, the masochistic, out there who wish to continue
developing TI PRCM code, I would ask that you resurrect any
additionally-needed macros from these commits, rather than writing
them manually. Purely for the sake of a pleasant atavism, perhaps; the
way one appreciates a used bookstore, or a video rental store...
And thanks to the upstream maintainers for being patient while we
adjust.

Nobody is using these mappings so just drop them. of_iomap() in
the timer driver will take care of it for us. Doing this allows
us to remove the 8x60 and 8960 iomap files completely.

This patch renames the old pwm-samsung driver to pwm-samsung-legacy to

As the need for an IRQ chip handling PWM timer interrupt chaining is
gone now, this patch removes all the code made unnecessary.

Current suspend/resume handling of the driver was broken, because:
- periodic timer was being enabled in CLOCK_EVT_MODE_RESUME mode, which
does not seem to be correct behavior looking at other platforms,
- PWM divisors need to be restored, but they were not,
- clockevent interrupt mask needs to be restored, but it was not,
- clocksource was being restored in clockevent resume callback.
This patch fixes issues mentioned above, making suspend/resume handling
in the driver correct.

PWM channel 4 has its autoreload bit located at different position. This
patch fixes the driver to account for that.
This fixes a problem with the clocksource hanging after it overflows because
it is not reloaded any more.
