ARM: S3C24XX: Move s3c2443-clock.c to mach-s3c24xx
From: Heiko Stuebner <heiko@...> Date: Sat, 3 Mar 2012 07:49:12 +0900
Commit-Message
S3C-SoCs starting with the S3C2443 can share a lot of functionality. The file can collect more common code of these SocS later on and therefore gets a new name to reflect this future purpose. Signed-off-by: Heiko Stuebner <heiko@...> Signed-off-by: Kukjin Kim <kgene.kim@...>
