The pm save/restore code is fairly small, so in order to
separate the s3c and s5p platforms, adding an s5p specific
copy instead of sharing it is actually easier.Signed-off-by: Arnd Bergmann

This is the only part of plat-samsung that is really
shared between the s3c and s5p ports. Moving it to
drivers/soc/ lets us make them completely independent.Signed-off-by: Arnd Bergmann

The pm-debug code is one of the few things shared between
s3c24xx/s3c64xx and the newer s5pv210. In order to make s5pv210
independent of plat-samsung, change the common bits of this code to no
longer reference the s3c specific bits.In particular, all the CPU checks need to be moved out of the common
code into platform specific files.Signed-off-by: Arnd Bergmann

On s3c24xx and s3c64xx, this is just a wrapper around
s3c_pm_debug_init_uart(), but this function does not exist on s5pv210,
which always uses an empty stub as CONFIG_SAMSUNG_ATAGS is normally
not set.In a configuration that supports both s5pv210 and s3c64xx, we would
always call the s3c64xx function, which is probably incorrect when
running on s5pv210.Remove the function call completely on s5pv210 and skip the wrapper on
s3c as a cleanup.As a side-effect, the s3c64xx behavior is now always the same, regardless
of whether it is a DT-only configuration or both DT and ATAGS are
supported for booting.Signed-off-by: Arnd Bergmann

A separate Kconfig option HAVE_S3C2410_WATCHDOG for Samsung SoCs is not
really needed and the s3c24xx watchdog driver can depend on Samsung ARM
architectures instead.The "HAVE_xxx_WATCHDOG" pattern of dependency is not popular and Samsung
platforms are here exceptions. All others just depend on
CONFIG_ARCH_xxx.This makes the code slightly smaller without any change in
functionality.Signed-off-by: Krzysztof Kozlowski

This patch moves pad retention control from S5PV210 machine code to
Exynos pin controller driver. This helps to avoid possible ordering
and logical dependencies between machine and pin control code. Till
now it worked fine only because sys_ops for machine code and pin

This replaces:
- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
now be selected directly.- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
is now selectable by everyone, so we need not declare our
intent to select it.When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".Cc: Michael Büsch

Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.Please notice the difference between
config ARCH_FOO
bool "Foo SoCs" if ARCH_MULTI_V7and
config ARCH_FOO
bool "Foo SoCs"
depends on ARCH_MULTI_V7These two are *not* equivalent!
In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns. This is probably not what
you want.The former should be used only when you need to do so, and you really
understand what you are doing. (In most cases, it should be wrong!)For enabling/disabling sub-architectures, the latter is always correct.
As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).[Arnd: I note that there is not really a bug here, according to
the discussion that followed, but I can see value in being consistent
and in making the lines shorter]Signed-off-by: Masahiro Yamada

The definition
static const char *axxia_dt_match[] __initconst = {
...defines a changable array of constant strings. That is you must not do:
*axxia_dt_match[0] = 'k';
but
axxia_dt_match[0] = "different string";
is fine. So the annotation __initconst is wrong and yields a compiler
error when other really const variables are added with __initconst.As the struct machine_desc member dt_compat is declared as
const char *const *dt_compat;
making the arrays const is the better alternative over changing all
annotations to __initdata.Signed-off-by: Uwe Kleine-König

The only remaining driver using the samsung dmadev code is the broken
samsung-ac97 sound driver. However, as found by Russell's autobuilder,
the elaborate dependency chains around it cause problems with
circular dependencies.This is an attempt to simplify those dependencies by making the
SAMSUNG_DMADEV option user-selectable. I also try to keep the
default settings for all related options unchanged, so we don't
introduce any regressions against earlier testing on linux-next.In particular, all s3c64xx and s5p* platforms keep selecting the
pl330 and pl08x drivers they require, but the select statement
is now moved towards the main platform option, and it remains
optional by unselecting CONFIG_DMADEVICES.Signed-off-by: Arnd Bergmann

It is not necessary to download these values to the maXTouch chip on every
probe, since they are stored in NVRAM. It makes life difficult when tuning
the device to keep them in sync with the config array/file, and requires a
new kernel build for minor tweaks.These parameters only represent a tiny subset of the available
configuration options, tracking all of these options in platform data would
be a endless task. In addition, different versions of maXTouch chips may
have these values in different places or may not even have them at all.Having these values also makes life more complex for device tree and other
platforms where having to define a static configuration isn't helpful.Signed-off-by: Nick Dyer
