Add dt-bindings for Imagination E5010 JPEG Encoder [1] which is implemented
as stateful V4L2 M2M driver.

The device supports baseline encoding with two different quantization
tables and compression ratio as demanded.

Minimum resolution supported is 64x64 and Maximum resolution supported is
8192x8192.

[1]:  AM62A TRM (Section 7.6 is for JPEG Encoder)

hmmm when did Rob give his reviewed by on this patch? (As this is not a
DT binding I find that odd)
And where is the Reviewed by tag from Benjamin that he provided on V5?

Greetings,
Sebastian

[PATCH v6 1/3] media: dt-bindings: Add Imagination E5010 JPEG Encoder : This
is indeed the dt-binding patch. Also As shared in version history it is at V4
where Rob Herring added a Reviewed-By as seen here [0]

> And where is the Reviewed by tag from Benjamin that he provided on V5?
> 

As captured in patch version history here [1] I thought to remove the
Reviewed-By since the Reviewed-By tag was on V5 and with V6 the driver got
updated with some changes to handle reported sparse warnings and so I have
asked Benjamin to check the range-diff and help with a quick review again if
possible.

Kindly let me know if I missed something or anything needs to be done from my end.

This is a DT binding, which is clearly expressed in subject prefix
(proper one) and the patch contents.

Yes thanks I was a bit too swift to write here, sorry for the noise.
We'll have a look.

Sorry for the back and forth, but on the hindsight and re-looking at the
kernel patch guidelines [0] they suggest that Reviewed-By tag should only be
removed if substantial changes were made in further revisions.

So looks to me in-fact it was a mistake on my part to remove the Reviewed-by
considering the change made in the following patch series was not a
substantial one as seen in the range-diff [1].

Considering this, just wanted to check with you if it's possible for you to
consider the Reviewed-by tag :
`Reviewed-by: Benjamin Gaignard <benjamin.gaignard@collabora.com`
if it helps consolidate things faster to get this series in given we are close
to final RC's ?

Yup I think we can keep it as the changes are very minor. Otherwise the
series is pretty much good to go, I'll prepare the PR asap.

Thanks, so I assume this could still make it to 6.9 merge window if it gets
pulled in before 6.8 rc8 ? Also do you think it would be possible to pull in
https://lore.kernel.org/all/20240305160529.4152865-1-devarsht@ti.com/ as here
too nothing much has changed w.r.t initial posting apart from commit message.
