Series adds driver support for Sony IMX519 sensor.

Lee, can do add S-o-B tags please to these patches
since I've updated your email IDs at various places from
info@ to lee.jackson@.

Thanks!

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC (and consider --no-git-fallback argument). It might
happen, that command when run on an older kernel, gives you outdated
entries. Therefore please be sure you base your patches on recent Linux
kernel.

A nit, subject: drop second/last, redundant "DT bindings". The
"dt-bindings" prefix is already stating that these are bindings.

Drop description, it's obvious.

That's not how this is done. Open existing bindings, e.g. imx219, 258 or
any other and look. Please, do not write patches entirely different than
all other drivers/bindings. There is a reason why some things work but
other don't

Can you dig and find out what your start point was here please?

This series should already be numbered at least v6, there are 5 previous
postings. The most recent of which was already Signed off by
'lee.jackson@arducam.com' So that makes me weary that v5 was not used as
the start point for this refresh.

Previous versions are identifiable here:

- https://patchwork.linuxtv.org/project/linux-media/list/?series=&submitter=&state=*&q=imx519&archive=both&delegate=

Could you check through any previous review comments and make sure they
have all been addressed too please?

It would be useful if the cover letter or patch described a changelog
from the previous version too to identify what has been updated.

I see the kernel test robot reported failures based on missing
dependencies.

It's helpful to list any dependency information here in the cover
letter too.

I second this. A summary of the major changes in the cover letter plus a
detailed changelog in each patch is invaluable for review.

You can use the --base argument to git-format-patch to record the base
commit, and point in the cover letter to a public branch where the
series can be found.

I think you should have, something alike (from mipi-ccs.yaml):

  port:
    $ref: /schemas/graph.yaml#/$defs/port-base
    additionalProperties: false

    properties:
      endpoint:
        $ref: /schemas/media/video-interfaces.yaml#
        unevaluatedProperties: false


See mipi-ccs.yaml on examples for some properties below. E.g.
link-frequencies is described in video-interfaces.yaml, no need to describe
it here.

I guess the device also supports single lane operation?

In any case minItems/maxItems here should be enough.
