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

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.

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

I call it:
dt-bindings: media: chips-media: add wave5 bindings
in V12
