[PATCH v4 5/6] dt-bindings: media: mediatek,vcodec-encoder: Add MT8196 with VCP support

[Irui Wang (王瑞)]

Dear Krzysztof,

I sincerely apologize for taking up your time to review and respond to
this patch. The maintainers' review comments are very important to us,
so we will never ignore them, there must be some misunderstanding in
this process.

From the reviews of v2 and v3, my understanding is that the patch lacks
details, so we add more description for current modification, for 'VCP'
usage. So we are very grateful if you could provide a `correct Subject
` example for us, thanks a lot.

If you are mean about the `else statement`, I left a comments and want
to get an explanation from you, if you feel that my reply is
unsatisfactory or incorrect, please let me know.

The key point is that our patch can satisfy you and get a Reviewed-by
from you.

Thanks
