In order to avoid spamming people too much, I'm only sending the first few patches of the patch series, and left the other patches for later. And if you are interested in the whole patch series, see: https://git.linaro.org/people/baolin.wang/upstream_0627.git Thoughts and feedback would be appreciated.
