were used anywhere.

Hello,

In this revision, the big change is in the 4th patch, where I followed Philipp Zabel's suggestions for i.MX7/8. The biggest change comes from the use of `v4l2_fill_pixfmt` to fill out the pixel format. Thanks to that, I could simplify the logic to select between 8-pixel- and 4-pixel-divisible line lengths. Thanks Philipp for pointing out this function, this is closer to what I originally hoped to do.

The use of `v4l2_fill_pixfmt` comes with the downside of breaking 10-bit Bayer formats, or at least until my other series gets accepted (Subject: "media: Add 16-bit Bayer formats". Sorry, I don't have the message id.).

Regards,
Dorota Czaplejewicz
