Thanks for review. I agree your point. In that case how about adding
"drivers/clk/samsung/Kconfig" as below:

+config COMMON_CLK_SAMSUNG
+ bool
+ select COMMON_CLK
+
+config S3C2412_COMMON_CLK //These macros are introduced by Heiko's
clock patches for S3C24XX SoC
+ bool
+ select COMMON_CLK_SAMSUNG
+
+config S3C2443_COMMON_CLK
+ bool
+ select COMMON_CLK_SAMSUNG

In this way we can get rid of clock related config options from
"arch/arm/mach-s3c24xx/Kconfig" and in future
if any other old SoC such as S5P clocks getting converted to use common
clock, they can add related config here rather
than arch/mach-xxx/Kconfig if required. Thus we can keep all common
clock config option for Samsung SoC at one place.
All Exynos SOC can select only COMMON_CLK_SAMSUNG to use Samsung common
clock infrastructure.
