[PATCH v4 0/4] Introduce new Kconfig for Samsung common clock

[PATCH v4 0/4] Introduce new Kconfig for Samsung common clock

[Pankaj Dubey]

Introduce a new Kconfig file for Samsung common clock infrastructure
related config options. As current Samsung common clock gets compiled
based on PLAT_SAMSUNG, but moving ahead with ARM64 we can not have any
more such config options, so this patch introduce new COMMON_CLK_SAMSUNG
invisible option. This option also select COMMON_CLK so ARCH Kconfig just
need to select COMMON_CLK_SAMSUNG in case they want to use Samsung common
clock.

This series is based on Kukjin's for-next branch.

I am just respinning this patch after rebasing. I have already addressed
all review comments discussed here [1].

[1]: http://lkml.org/lkml/2014/3/19/216

V4:
 1) Rebased on latest Kukjin's for-next branch.

V3: 
 1) Re-organized patches for preventing bisect issues.
 2) Rebase on top of latest Kukjin's for-next branch.
 3) Compile tested exynos_defconfig, s3c6400_defconfig and s3c2410_defconfig
    after each commit.

V2:
 1) Adding new Kconfig file for Samsung common clock.
 2) Make COMMON_CLK_SAMSUNG option invisible. (as suggested by Tomasz Figa)
 3) Let COMMON_CLK_SAMSUNG select COMMON_CLK. (as suggested by Tomasz Figa)
 4) Move S3C24XX clock config option in new Kconfig file.
