As you can see from my replies I only have a few small review comments remaining.

Can you fix it and post a v4 (rebased to the latest kernel)? Please also add the
v4l2-compliance -f output to the cover letter.

Unless I see something new I plan to make a pull request of v4 for 4.9.

I hope to post my conversion of the atmel-isi driver soon, and that might give
you some ideas on how to get rid of the soc-mbus stuff in a follow-up patch.
