[Hiremath, Vaibhav] Sakari,
Can you share your version of code (either in form of patches or source) here onto the mailing list, so that everybody those who are interested will be aware of changes?

Atleast for me I would get prior view of changes which might affect BT656 support (posted on top of Sergio's patch).

Again one more thing I would like to bring to your notice is about sub-device framework. Also we need to plan for the migration from V4L2-int to sub-device framework, which is of equal important. I feel the more time we spend in merging and aligning offline, more we are carrying risk.

According to me as I mentioned before, the plan should be to push ISP-Camera with V4L2-int interface as early as possible with whatever minimal sensor/decoder support we have today, which will make sure that our underneath ISP-library is in place. Once that is placed in, we can have additional patches on top of it to add more features. 

In this way, we can plan for migration to sub-device framework and also be easier and simpler. Even if any customers are interested, they can pick it up the ISP library and start development on top of it.
