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,
