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.

hmmm when did Rob give his reviewed by on this patch? (As this is not a
DT binding I find that odd)
[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.
Yes thanks I was a bit too swift to write here, sorry for the noise.
We'll have a look.
Greetings,
Sebastian

+description: |
+ The E5010 is a JPEG encoder from Imagination Technologies implemented on
+ TI's AM62A SoC. It is capable of real time encoding of YUV420 and YUV422
+ inputs to JPEG and M-JPEG. It supports baseline JPEG Encoding up to
+ 8Kx8K resolution.
