Ben Dooks 229fd8ffba ARM: S3C24XX: Add FIQ IRQ routing support
Add support for routing an IRQ from the normal ARM IRQ mechanism to the
FIQ input of the processor.

Note, also fix a bug where the init_FIQ() function has not been called
when CONFIG_FIQ is enabled.

Peter Korsgaard 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.

Ben Dooks 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'

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.

Russell King 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.

Ben Dooks fff94cd9f5 [ARM] S3C: Tidy sleep code path to fix call flow
As noted by Russell King, the sleep code path is not
elegant and makes use of leaving items on the stack
between calls.

Change the code that does the following:

        if (s3c_cpu_save(regs_save) == 0) {
                flush_cache_all();
                S3C_PMDBG("preparing to sleep\n");
                pm_cpu_sleep();
        }

to simply call s3c_cpu_save, and let that do the
necessary calls to quiesce and sleep the system.

Ben Dooks d2b07fe2a3 [ARM] S3C: Update UART save over PM suspend/resume
Change the way the UART state is saved over suspend to allow the s3c64xx
code to modify the settings on resume to avoid any illegal state changes
to the UART clocks. This will also allow us to save the UDIVSLOT register
on newer SoCs.

Move to using a structure for the UART use the extant Kconfig configuration
specifying the number of UARTs.

The S3C64XX timer is running at the wrong rate due to the

Fix the problem by moving to using the clk framework to setup

Ben Dooks 74b265d4e0 [ARM] S3C24XX: Move initialisation code to arch/arm/plat-s3c
We need to add plat-s3c to the build to get the headers
that will go in here once moved from include/asm-arm so
we may as well put some useful common s3c code in here
to stop the errors generated form having nothing built.

The cpu setup is now passed the cpu idcode and the table
of supported cpus to s3c_init_cpu() to abstract the
cpu identification out of the initial io setup.

As well as moving the cpu initialisation code, we move the
map of the board specific items up to the calling code as
none of the map_io() functions actually do anything other
than pass this to iotable_init().

This patch does not rename any of the init functions that
will be common to s3c24xx and any other s3c architectures
as this can be done at a later date as it will touch all
the board support files which use functions such as
s3c24xx_init_clocks() and s3c24xx_init_uarts().

Note, the header arch/arm/plat-s3c24xx/include/plat/cpu.h
still has functions that are used by both the cpu and
board initialisation functions. This means that each board
has definitions specific to the cpu support included and
the vice-versa.
