ARM: S3C24XX: convert s3c2440 and s3c2442 to common clock framework
From: Heiko Stuebner <heiko@...> Date: Thu, 12 Dec 2013 22:09:37 +0100
Commit-Message
Convert all machines using these cpus to use the ccf clock driver instead of the legacy Samsung clock implementation. Some of the more esotheric machines will probably need a fixup, as they do strange things to the clkout outputs, that I did not really understand nor have the hardware to check.
