Thank you for your kind assistance, I have created a tree which checkout from the next-20151019. Surely there were some conflicts to applied this series on that tag, but things still works for me, here is the git address [https://github.com/yakir-Yang/linux/tree/analogix_dp] Best regards, - Yakir > > Best regards,
