Currently I see it at v3.18-rc1. And the series rebases cleanly onto it with no differences. I'm guessing some of Maxime's cleanup work is the source of conflict.

Hi ChenYu, The patches look fine to me so I tried applying them but they fail to apply, can you please rebase these two and resend Thanks -- ~Vinod -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.

Hi, Vinod, Any chance we can get patches 1 & 2 merged? You've already merged the prerequisite patch "dmaengine: sun6i: Remove obsolete clk muxing code" a few days ago, and patch 3 is already in arm-soc. Thanks!
