As no one is answering my question even after two days, I'm going to answer it by myself. This might help someone who is struggling to find the answer to the same question.
01) Latest Android 7.1 has drivers for the 3.5mm audio input as well as the stereo output.
02) The 3.5mm jack in pine64 board is of OMTP varient (Not CTIA as depicted in the data sheet). You can use NOKIA, Huawei or old Samsung headsets but don't try Apple or newer Samsung headsets.
03) The jack is not a high quality one so you may have to twist and shake a little to achieve good contact.
I'll post new updates of my project of making google home device out of pine64 2GB board.
Good luck.
