I am waiting for more comments for the sunxi-csi.h. It's pleasure if
you have any suggestions about it.

You mean sunxi_csi.h, right?

Yes. My spelling mistake.

Why do you need the sunxi_csi_ops indirection? Do you expect to add 
alternative implementations of these ops at some point?

I want to seperate the sunxi_video.c and sunxi_csi_v3s.c. 
sunxi_csi_v3s.c is Soc specific. Maybe there will be sunxi_csi_r40.c
in the futrue. But the sunxi_video.c and sunxi_csi.c are common.

I'd say it is a premature optimization. The file separation is fine, IMO, but 
the added csi_ops indirection makes the code less readable. Someone with 
access to R40 hardware with CSI setup would be a better position to abstract 
the platform specific code.

But I'd defer to the media maintainers on that.

Thanks,
baruch
