165f5f6419 ARM: S3C: PWM fix for low duty cycle
The pwm hardware only checks the compare register after a decrement,
so the pin never toggles if tcmp = tcnt.

This happens when a very low duty cycle is requested. Fix it by always
ensuring that tcmp < tcnt.

Move all the gpio functions out of <mach/hardware.h> as

what most of these files should be using (and will be
changed as soon as possible).

Note, this does make minor changes to some drivers but
should not mess up any pending merges.

9f05f6a921 [ARM] S3C24XX: GPIO: Remove pin specific input and output defines
The use of S3C2410_GP[A-Z]x_INP and S3C2410_GP[A-Z]x_OUTP are
very rare and are taking up large amounts of space in the
regs-gpio.h header.

The GPIO layer has had generic input and out defines called
S3C2410_GPIO_INPUT and S3C2410_GPIO_OUTPUT for a while which work
for all S3C24XX GPIOs.

Do the following replacements:

   S3C2410_GP[A-Z][0-9]*_\OUTP => S3C2410_GPIO_OUTPUT
   S3C2410_GP[A-Z][0-9]*_\INP  => /S3C2410_GPIO_INPUT
   S3C2410_GPA[0-9]*_OUT       => S3C2410_GPIO_OUTPUT

to remove any usages of these and prepare the header for
the removal of these.

The following command was used to acheive this:

find . -type f -writable ! -name regs-gpio.h ! -name "*~" | xargs sed -i~ -e 's/S3C2410_GP[A-Z][0-9]*_\OUTP/S3C2410_GPIO_OUTPUT/g' -e 's/S3C2410_GP[A-Z][0-9]*_\INP/S3C2410_GPIO_INPUT/g' -e 's/S3C2410_GPA[0-9]*_OUT/S3C2410_GPIO_OUTPUT/g'

This patch allow us to efficiently modify the number of
remaining conversions from the client side. This us useful
when we do not know in advance how many conversions we will
need or when we need to cancel pending conversions.

This change is simple enough to be compatible with existing

and ignore it.

d87964c460 [ARM] S3C: GPIO PM core GPIOlib integration
Move the GPIO suspend/resume support inline with the gpiolib support
so that it will work with both the S3C24XX and S3C64XX series.

The s3c_gpio_chip is extended to have a pm callback and a save block
to keep the state of the GPIO over suspend, and the code from the
s3c24xx implementation is added to a new common file.

The suspend process now uses the list of registered chips to go through
saving and restoring each one as appropriate, using the pm callback to
select the appropriate routine depending on the type of control register
present.

This change also means that any additional GPIO added should not require
changes to the PM.

be093beb60 [ARM] pass reboot command line to arch_reset()
OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.
