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.

rk3399 platform have dfi controller can monitor ddr load,

right ddr frequency and make ddr controller happy work(which
will implement in bl31). So we do ddr frequency scaling with
following flow:

kernel bl31

monitor ddr load

get_target_rate

| pass rate to bl31
clk_set_rate(ddr) --------------------->run dcf flow

wait dcf interrupt<-------------------trigger dcf interrupt

The cover-letter includes the duplicate list of patches.

Also, I want to test the build test. but, When I apply these patches,
merge conflict happen. Could you give the information about base git repository?
