Hi Laurent,
I agree that the find/enum format code in imx-utils needs cleanup, it's
too confusing. I will be ready to give my ack to the imx-utils patches
once I do some smoke testing on a sabre target when I return from vacation.
Note that Phillip also submitted a fixup patch to the find/enum format
code, IIRC it did more consolidating of the imx_media_pixfmt tables. I
can't find it and it has gotten lost, but I tested and provided a
reviewed-by at the time.
I've found them in the mail archive. There were 3 patches, Hans said he
would take the first two, but only the first one got merged. I'll take
the two others and build on top of them, fixing the issues pointed out
by the kbuild robot and addressing Hans concerns.
I found the thread finally. In fact I did some work on this set already,
I fixed the kbuild warnings as well as added some function headers
describing all the format search criteria arguments. Also changed a
local var in enum_formats() to better document the enum algorithm.
Unless you've started on this work already, I will be returning from
vaca tomorrow and can pick this up again, merging in your patches, as
well as splitting up find|enum_formats() into find|enum_formats() and
find|enum_codes(), which is the remaining suggestion from Hans.
I've done this already, I'll try to send the patches on Monday.
If you don't mind, I've done this work and tested on an imx6 target. So
I will post a series.

Hello,
This patch series started as an attempt to fix the format get and set
subdev operations on the i.MX7 CSI-2 receiver subdev, which it does in
patch 1/8. Patch 2/8 further cleans up the format-related code in that
subdev.
Patches 3/8 to 8/8 pushes the cleanups further as I was attempting to
fix the format enumeration on the video node at the end of the pipeline.
I realized as part of that effort that there's more work than I
anticipated, and I'm currently evaluating the possible options.
Nonetheless, I think the cleanups make sense even without what I wanted
to build on top of them, so I'm sending them out already.
