Along with Devfreq/Passive patchset, the patchset is merged in
devfreq for-4.7 tree.
https://git.kernel.org/cgit/linux/kernel/git/mzx/devfreq.git/log/?h=for-4.7
@Chanwoo: If there are commits to be merged by a tree other than Linux/PM,
please let me know. I'll send out pull-request soon.
Cheers,
MyungJoo

As we discussed before, don't apply the DTS changes. The DTS are
independent so they should go through samsung/arm-soc.

Another point is that you applied patches without your signed-off-by...
that is not the proper way. If you touch a patch or apply it, you must
signed it off.

... and now I noticed that you also applied clock patches. Please don't.
They are for some time in clk tree. Sylwester prepared a tag for that,
if you need one.
Best regards,
Krzysztof

On Krzysztof Kozlowski's reply, dts patches will be merged on samsung-soc tree.
and then the clock patches about exynos5420 was already merged to samsung-clk tree
by Sylwester.
Only devfreq patches should be merged on devfreq tree.
We already discussed this topic on offline. I expect that you will again handle
this patchset according to reply of both Krzysztof and me.
Best Regards,
Chanwoo Choi
