What's happening with this patch? Where is the changelog?

The changelog is located in the cover letter.
https://lore.kernel.org/linux-media/20221207121350.66217-1-sebastian.fricke@xxxxxxxxxxxxx/

Why it is v11 and first time I see it?

You actually replied to V10:
https://lore.kernel.org/linux-media/20221023085341.s23qinjuw4qls3dn@basti-XPS-13-9310/

And why it is v11 with basic mistakes and lack of testing?!?
I would assume that v11 was already seen and tested...

Sorry I don't have a lot of experience with dt-bindings, thank you for
highlighting the issues, I will correct them. And I forgot to build the
documentation during my testing runs.
I took over the patch set from another contributor and as no one
complained about the dt-bindings for the last 10 versions, I concentrated
my energy on other problems.

Wrong directory. It wasn't here at all before, so I am really confused
how this could happen.

Thanks for the highlight.

I will move it to:
Documentation/devicetree/bindings/media/cnm,wave5.yml


Subject: drop redundant pieces: yaml, devicetree and bindings.

I call it:

dt-bindings: media: chips-media: add wave5 bindings

in V12

Sincerely,
Sebastian Fricke

What's the difference between this and one above?

This has to be specific.

+
+  clock-names:
+    minItems: 1

You need to list the names.

And what is it for? Why do you need SRAM?
