Heiko Stuebner f6361c6b38 ARM: S3C24XX: remove separate restart code
The restart-handler series from Guenter Roeck got accepted recently and
implements among other things also the restart handler in the samsung
watchdog driver and where applicable in the clock drivers. So there is
no need for having the restart callbacks in s3c24xx boards anymore.

Heiko Stuebner 07ee5e7c3e ARM: S3C24XX: convert s3c2410 to common clock framework
Convert the machines using the s3c2410 to use the new driver based
on the common clock framework instead of the legacy Samsung clock driver.

As with the s3c244x, machines using the clkout output will need a fixup
from someone with the hardware.

Heiko Stuebner 51cb128987 ARM: S3C24XX: enable usage of common dclk if common clock framework is enabled
Add platform device and select the correct implementation automatically
depending on wether the old samsung_clock or the common clock framework
is enabled.

This is only done for machines already using the old dclk implementation,
as everybody else should move to use dt anyway.

The machine-specific settings for the external clocks will have to be set
by somebody with knowledge about the specific hardware.

Linus Walleij b0161caa72 ARM: S3C[24|64]xx: move includes back under <mach/> scope
When refactoring and breaking out the includes for the
machine-specific GPIO configuration, two files were created
in <linux/platform_data/gpio-samsung-s3c[24|64]xx.h>, but as
that namespace shall be used for defining data exchanged
between machines and drivers, using it for these broad macros
and config settings is wrong.

Move the headers back into the machine-local
<mach/gpio-samsung.h> file and think about the next step.

Linus Walleij c67d0f2926 ARM: s3c24xx: get rid of custom <mach/gpio.h>
This isolates the custom S3C24xx GPIO definition table to
<linux/platform_data/gpio-samsung-s3x24xx.h> as this is
used in a few different places in the kernel, removing the
need to depend on the implicit inclusion of <mach/gpio.h>
from <linux/gpio.h> and thus getting rid of a few nasty
cross-dependencies.

We also delete the nifty CONFIG_S3C24XX_GPIO_EXTRA stuff.
The biggest this can ever be for the S3C24XX is
CONFIG_S3C24XX_GPIO_EXTRA = 128, and then for CPU_S3C2443 or
CPU_S3C2416 32*12 GPIOs are added, so 32*12+128 = 512
is the absolute roof value on this platform. So we set
the size of ARCH_NR_GPIO to this and the GPIOs array will
fit any S3C24XX platform, as per pattern from other archs.

ChangeLog v2->v3:
- Move the movement of the S3C64XX gpio.h file out of
  this patch and into the follow-up patch where it belongs.
ChangeLog v1->v2:
- Added an #ifdef ARCH_S3C24XX around the header inclusion
  in drivers/gpio/gpio-samsung.c as we would otherwise
  have colliding definitions when compiling S3C64XX.
- Rename inclusion guard in the header file.

Heiko Stuebner f182aa1dfa ARM: S3C24XX: move s3c24xx_init_irq to s3c2410_init_irq
The s3c24xx_init_irq function that was the base for all irq inits
is now only used to initialize the real s3c2410 irqs.

Therefore rename it and also move its declaration from plat/cpu.h
to common.h

The eint declaration is used by the vast majority of the SoCs and
gets therefore placed outside any ifdefs.

Stephen Warren 6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.

Heiko Stuebner ec2cc753f4 ARM: S3C24XX: Consolidate Simtec extensions
The Simtec extension didn't follow a specific naming scheme for files
and config options until now. This distributed the files throughout
the whole mach-s3c24xx directory.

This patch fixes the naming of files and option names and also creates
a simtec.h header instead of using many one-liners.

As the plat/audio-simtec.h only contains the platform-data struct now,
it can also move to include/sound in a later patch.
