Hi Krzysztof,

Thank you for your comments.

I am talking about CSI-related patches 1-5, not including the patches
6-8. The CSI module is a relatively functionally independent hardware
module. The CSI-related patches 1-5 already have 'reviewed-by' tags,
and there are no unprocessed comments left. So, made the previous
request. Please let me know if I understand something wrong.

I don't want to ignore any comments, I will continue to modify the isp
patches 6-8 in subsequent versions according to your comments. The
ISP-related patches are being prepared.

Jack
