[PATCH v4 0/7] rk3399 support ddr frequency scaling

[hl]

Hi Chanwoo Choi,

     Ah, i am base on 
https://chromium.googlesource.com/chromiumos/third_party/kernel/v4.4,
and forget to rebase on 
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git, i 
will fix it in next version.
I am sorry about that. And can you help to review the devfreq patch 
first, if something need to update,
i will do it together. Thanks.
