But what about the depends and the help text?
If I just enable the following config options in multi_v7_defconfig and
remove that depends, the driver will not build because the {dvfs,freq}_table
definitions only get added to the final source file when CONFIG CPU_S3C6410 is
set...
CONFIG_ARCH_MULTI_V6=y
CONFIG_ARCH_S3C64XX=y
CONFIG_MACH_SMDK6400=y

So maybe it _should_ support s3c6400 but it does not appear to, which
is why there is this clang warning that my patch is trying to address.
If I am missing something critical, please let me know.
Cheers,
