Hi James

Thanks for your patch, you should:

- Provide a more descriptive commit message
- Add the new format to the documentation
- Split the uvc changes with the videodev changes
- Keep some kind of alphabetic order in the formats

You could take a look to 0376a51fbe5e11a59d6a5c55e57cc201da06dbe0
media: v4l: Add packed YUV444 24bpp pixel format  for inspiration

Regards
