Is that no longer used now? I assume the patch is correct based on Krzysztof's review, but it might be good to explain this better.

Yeah, that's old driver, no longer existing. It makes sense to split the patch - first remove the stale exynos-cpufreq and then move cpufreq-dt. This would help avoid confusion when grepping through the history.
