[Hiremath, Vaibhav] Hi Hans and others,
I think I have cleaned up all my VPFE patches today, Can you merge it to your
repo. Below is the list -
[PATCH V2] VPFE Capture: Add call back function for interrupt clear to vpfe_cfg
[PATCH] Davinci VPFE Capture: Add Suspend/Resume Support
[PATCH] DM644x CCDC: Add 10bit BT support
Patches still open -
- Can you comment on the patch "[PATCH] Introducing ti-media directory"?
If all are agree to this then I can move other files to this directory.
- Switch to automode in query_std, I think at the end we mentioned that, if we
can put a constraint on application that, user can not query_std when streaming
is going on, it should be fine. Can I resubmit the patch?
Thanks,
Vaibhav
