Break each binding document to an independent patch and this would make review process easier.
For example, there are five patches for each of cam-raw, cam-yuv, camisp, seninf-core, seninf.
When I feel good about cam-raw, cam-yuv, camisp, I would give reviewed-by tag on these three patches.
After you send new version, I could focus on reviewing seninf-core and seninf.

If these are combined into one patch, even I feel good about cam-raw, cam-yuv, camisp, I can not give reviewed-by tag on this patch.
After you send new version, I need to review the whole patch again. This would slow down the review process.
