Re: [PATCH v5 00/49] DaVinci: vpif: upgrade with v4l helpers and v4l compliance fixes
Hi Prabhakar, Thanks for this patch series, it looks good to me and I'll make a pull request for this. I did find a few issues, but they are all pre-existing problems, so they can be fixed in follow-up patches. I'll comment on those in the relevant patches. Since display and capture are so similar I will only comment on the display patches, but it's valid for both.

Hi Hans, Thanks for the review from 2 patches to 50 :) On Fri, May 23, 2014 at 2:00 PM, Hans Verkuil hverk...@xs4all.nl wrote: Hi Prabhakar, Thanks for this patch series, it looks good to me and I'll make a pull request for this.

Ok will fix them up soon I am relocating next week so will take me at-least 2-3 weeks for me to get back the boards and get in action.
