NAK.

Nicolas gave you important feedback on your first version,
and you have ignored that, as far as I can see.

It seems very rude to do that, please avoid ignoring
feedback from reviewers and maintainers.

https://www.spinics.net/lists/linux-media/msg196342.html

Please move the driver to drivers/media/platform/amphion,
rename the driver name, compatible, etc. This is the same
case as CODA driver, Hantro driver, etc.

I sincerely hope you will not ignore this, and then send a v8 version ;-)

Thanks!
Ezequiel
