Hi Laurent, Tomasz, Matthias,

gentle ping for this patch set,
If no new comments, I would like to send a newer version.

Sorry, I still haven't had a chance to look at the series, so feel
free to send a new version and I will take a look at the new one.

Finally found some time to review the series. Again sorry for the delay
and thanks for your patience.

Some general comments:
1) The metadata format FourCC should be added in a separate patch,
together with documentation for it.
2) Control IDs, structs used by the userspace, etc. should be defined in
a header under include/uapi/linux.

Please also check my replies to particular patches for further comments.

Best regards,
Tomasz

Appreciate for your reply,

So far, I've locally created an uapi header:
include/uapi/linux/mtk_fd_40.h
which provides some values, control ids, and the definitions of
structures that would be needed by user of mtk_fd_40 driver.
In addition, I also provide a MACRO as example in comments that can
extract the struct member with bit length and offset
definitions(eliminate the bit-fields).

Also, I would like to rename struct fd_user_output with struct
mtk_fd_hw_result. I worry fd_user_output would be a confusing name.
I will add them in a separate patch in next version.

I am still working on the documentation, which might be
Documentation/media/uapi/v4l/pixfmt-meta-mtk-fd-40.rst.
Refering the other pixfmt-*.rst files, I will try to provide the
flat-table of the metadata with the structure of the mtk_fd_hw_result.

I am confusing that should I remain the name with -40 in the tail of rst
file?
Since I think the layout of metadata might be different in the future
mtk fd drivers. Maybe they create a new one or should they update the
rst file when they are upstreaming?

Other comments are almost fixed, I will inform you by this mail thread
as soon as I finish the documentation of fd metadata format.

Sorry for the late response,
Thanks and Best Regards,
Jerry
