This patch series adds initial support for CPU frequency scaling using
the ARMCLK divider on the S3C64xx CPUs. Currently only S3C6410 is
supported - adding S3C6400 should be a matter of providing the list of
frequencies supported by that CPU.
I have included Kyungmin Park's CPU detection support patch in the
series since the divider for ARMCLK differs between S3C6400 and S3C6410
and forcing only one of them to be used using ifdefs seemed to be undue
pain.
I'm currently working on and testing additional patches to further
enhance this but I wanted to post these first in order to make sure I'm
not completely off-base here.
