Then I would want to finish up with OMAP3 Display driver part before moving to Media Controller support for MEM-to-MEM (like, Resizer).
Just FYI, I will be going for vacation for 1 & 1/2 week starting from coming Friday. But I will make sure that I will submit patches for Display (OMAP3 & AM3517) and AM3517 Capture driver before that.
