Cc'ed Ben Dooks.

No. Please don't add this in arch/arm. If required, they should be
added in drivers/cpufreq/ like x86.

As a note, I'm sorting that out which includes all of Samsung cpufreq
driver.

Dave, could you please see below? If you're ok, will submit remained
others for Samsung cpufreq drivers.

Thanks.

Best regards,
Kgene.

Subject: [PATCH] cpufreq: Add Samsung cpufreq driver compile in Kconfig.arm

According to discussion of the ARM arch subsystem migration,
ARM cpufreq drivers move to drivers/cpufreq. So this patch
adds Kconfig.arm for ARM like x86 and adds Samsung cpufreq
driver compile in there.

As a note didn't add 'default y' on this to build error during
each maintainers' merge. If required, it can be added later.
