soc-camera and videobuf2

Reposting.  Sorry for the rich text in my previous email.

I'm looking at the videobuf2 stuff, and would like to use it because it solves a bunch of problems for me that were in videobuf (for example, I'm writing a variant of videobuf-dma-contig, and there's some private memory allocator state I needed to track, but the videobuf stuff didn't seem to let you do that).

But I'm also using soc_camera.  I was wondering if there's a time estimate for soc_camera to be converted over to the videobuf2 framework.

Also, are SoC camera host drivers expected to call the methods in the videobuf2 ops table directly (as in, vb2_ops->alloc())?  Or will there be wrappers around these in the future (the wrappers can take the videobuf2's alloc_ctx as a parameter and thereby figure out which method to call).
