This patch add support for EXYNOS5250 SoC has two Cortex-A15 cores.
Since actually, most codes in mach-exynos/ are used commonly for
EXYNOS4 and EXYNOS5 the EXYNOS5/EXYNOS5250 has been implemented
in mach-exynos/.

The dma controller is similar in S3C2443 and S3C2416 and has also
the same register layout with the same REQSEL-bits in the source
select.
The only small difference is the SIO channel of the S3C2443 for the
non-hsmmc controller which is not present on S3C2416/2450 and
second spi channel which is not present on the S3C2416.

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.

This patch adds s3c_fb_driverdata s3c_fb_data_exynos5 for EXYNOS5
and adds extended timing control setting.
EXYNOS5 FIMD needs extended setting for video timing control.
Additional bits are added to VIDTCON2, VIDWxxADD2, VIDOSDxA and
VIDOSDxB registers in order to set timing value for lager resolution.
Also, address offset of VIDTCONx registers is changed from 0x0
to 0x20000, thus variable type should be changed to int type
to handle the address offset of VIDTCONx registers for EXYNOS5 FIMD.

Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite. Remove arm_machine_restart() as this function
no longer does anything useful.
For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions. As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove

Instead of using clock names supplied in platform data, use a generic
clock name 'clk_uart_baud' to look up clocks. The platform code should
register clocks with the name 'clk_uart_baud' which can be used by the
baud rate generator. The clock lookup and selection of the best clock
as baud rate clock is reworked.
Platform code can specify the clocks that can be used as source for the
baud clock (as supported previously by passing names of clocks). A new
member is added to the platform data 'clk_sel' which holds a bit-field
value with each bit representing a baud source clock. If a bit at any
bit position is set, that clock is looked up to participate in the
selection of the baud clock source.

The S3C64xx SoCs contain a set of gateable power domains which can be
enabled and disabled at runtime in order to save power. Use the generic
power domain code to implement support for these in software, enabling
runtime control of most domains:
- ETM (not supported in mainline).
- Domain G: 3D acceleration (no mainline support).
- Domain V: MFC (no mainline support).
- Domain I: JPEG and camera interface (no mainline support).
- Domain P: 2D acceleration, TV encoder and scaler (no mainline support)
- Domain S: Security (no mainline support).
- Domain F: LCD (driver already uses runtime PM), post processing and
rotation (no mainline support).
The IROM domain is marked as always enabled as we should arrange for it
to be enabled when we suspend which will need a bit more work.
Due to all the conditional device registration that the platform does
wrap s3c_pm_init() with s3c64xx_pm_init() which actually puts the device
into the power domain after the machines have registered, looking for
platform data to tell if the device was registered. Since currently only
Cragganmore actually sets up PM that is the only machine updated.

The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.
This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.

The IS_SAMSUNG_CPU() macro works by comparing the CPU ID mask exactly with
the CPU ID. This was failing for S3C64xx SoCs as in order to support
identification of the exact device the mask covers both variants of the
chip, meaning that the test would always fail on S3C6410 devices. This in
turn caused the core GPIO subsystem to fail to identify the CPU and not
support any GPIOs, crippling the system.
As a minimally invasive fix change the test for the class to be done by
checking each implementation and oring them together.

This patch adds common DMA operations which are used for Samsung DMA
drivers. Currently there are two types of DMA driver for Samsung SoCs.
The one is S3C-DMA for S3C SoCs and the other is PL330-DMA for S5P SoCs.
This patch provides funcion pointers for common DMA operations to DMA
client driver like SPI and Audio. It makes DMA client drivers support
multi-platform.
In addition, this common DMA operations implement the shared actions
that are needed for DMA client driver. For example shared actions are
filter() function for dma_request_channel() and parameter passing for
device_prep_slave_sg().

There are SoCs where attempting to enter a low power state is ignored,
and the CPU continues executing instructions with all state preserved.
It is over-complex at that point to disable the MMU just to call the
resume path.
Instead, allow the suspend finisher to return error codes to abort
suspend in this circumstance, where the cpu_suspend internals will then
unwind the saved state on the stack. Also omit the tlb flush as no

This patch fixes the way of comparison for handling of two or more
clock sources for UART.
For example, if just only one clock source is defined even though
there are two clock sources for UART, the serial driver does not
set proper clock up. Of course, it is problem.
So this patch changes the condition of comparison to avoid useless
setup clock and adds a flag 'NO_NEED_CHECK_CLKSRC' which means
selection of source clock is not required.
In addition, since the Exynos4210 has only one clock source for UART
this patch adds the flag into its common_init_uarts().

To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols. This usually means that no global variables can
be marked static unless they're also const.
Let's remove the static qualifier from current offenders, or turn them
into const variables when possible. Next commit will ensure the build
fails if one of those is reintroduced due to otherwise enforced coding
standards for the kernel.

Replace sysdev classes and struct sys_device objects used for "core"
power management by Samsung platforms with struct syscore_ops objects
that are simpler.
This generally reduces the code size and the kernel memory footprint.
It also is necessary for removing sysdevs entirely from the kernel in
the future.

This patch removes all global data from common s5p gpio interrupt
handler code. This enables to reuse this code on EXYNOS4 platform.
Instead of global data (IRQ_GPIOINT interrupt number,
S5P_GPIOINT_GROUP_MAXNR groups count), a s5p_register_gpioint_bank()
function is introduced. It is aimed to be called from gpiolib init.

Currently the {set,get}_pull callbacks of the s3c24xx_gpiocfg_default structure
are initalized via s3c_gpio_{get,set}pull_1up. This results in a linker
error when only CONFIG_CPU_S3C2442 is selected:
arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f4): undefined reference to
`s3c_gpio_getpull_1up'
arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f8): undefined reference to
`s3c_gpio_setpull_1up'
The s3c2442 has pulldowns instead of pullups compared to the s3c2440.
The method of controlling them is the same though.
So this patch modifies the existing s3c_gpio_{get,set}pull_1up helper functions
to take an additional parameter deciding whether the pin has a pullup or pulldown.
The s3c_gpio_{get,set}pull_1{down,up} functions then wrap that functions passing
either S3C_GPIO_PULL_UP or S3C_GPIO_PULL_DOWN.
Furthermore this patch sets up the s3c24xx_gpiocfg_default.{get,set}_pull fields
in the s3c244{0,2}_map_io function to the new pulldown helper functions.
