[PATCH v2 15/41] ARM: exynos: stop selecting PLAT_SAMSUNG

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

Now that no code in arch/arm is shared between mach-exynos and the
others, make the split formal.

[PATCH v2 18/41] ARM: s5pv210: don't imply CONFIG_PLAT_SAMSUNG

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

The plat-samsung directory and mach-s5pv210 can be build
completely independently, so split the two Kconfig symbols
CONFIG_PLAT_SAMSUNG and CONFIG_ARCH_S5PV210.

[PATCH v2 29/41] ARM: s3c24xx: move s3cmci pinctrl handling into board files

[Krzysztof Kozlowski]

From: Arnd Bergmann <arnd@arndb.de>

Rather than call the internal s3c_gpio_cfgall_range() function
through a platform header, move the code into the set_power
callback that is already exported by the board, and add
a default implementation.

In DT mode, the code already does not set the pin config,
so nothing changes there.

[krzk: Rebase and correct set_power in mach-h1940.c]

Changes since v1:
1. Minor whitespace changes,
2. mach-h1940.c already had set_power.
