Hmm, this does not look like config for kernel neither from Linus' nor
linux-next tree. The first thing I can see is CONFIG_ARCH_EXYNOS_MULTI
selected, which is not available in any mainline tree.
As for the build error itself, headers from plat/ are available for drivers
only in single platform builds, they can't be included when multiplatform
is enabled. The exynos-cpufreq driver is not multiplatform-aware yet and so
you get the failure.
Best regards,
Tomasz
