But the v6 version of that series will be merged once the 4.20 cycle opens: https://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg133391.html Sakari has a branch with that series on top of the latest media_tree master: https://git.linuxtv.org/sailus/media_tree.git/log/?h=v4l2-fwnode Can you rebase this imx7 series on top of that? And test it again with the *latest* v4l2-compliance? (I've added new checks recently, so you need to update this utility) Please post the output of the v4l2-compliance test (after fixing any issues it raises of course), either as a reply to this post or in the cover letter of a v7 version of this series if you had to make changes. This should expedite merging this series for 4.20. Thanks! Hans
