Chris,

TI has plan to up port the driver to the git tree which will add raw mode. We 
are using  v4l2-int-device for the interface to attach decoders to the front 
end master driver. There are some finer details being worked out before pushing 
the patch to the tree. You may check the v4l2 mailing list to track this.

Subject: VPFE raw mode status in the git tree

Greetings,

Examining the VPFE driver in the git tree (as of 
832e2db0642e148d8a30ec998c1e38910a96acc4) and the list archives, it looks as 
though support for the CCDC's raw mode was removed during the forward port from 
the Montavisa 2.6.10 version. It also seems that there are some other folks out 
there (besides me) interested in hooking up devices besides the tvp5146 that 
ships on the DVEVM, which leads me to ask a few questions:

1. Is anyone on the davinci-linux-open-source list currently working on adding 
raw mode to the VPFE in a manner that might fly with upstream maintainers?

2. How should the driver be restructured to accommodate both? The current git 
tree driver (as of 832e2db0642e148d8a30ec998c1e38910a96acc4) ties in the 
tvp5146 pretty tightly, and the old (2.6.10-mvl?) version did the same for both 
the tvp5146 and mt9t0001. It looks like we might follow the example of some of 
the OMAP devices and PXA270 have generic video front-ends similar in concept. 
They treat their video front-ends like busses that may have any sensor or video 
decoder attached... except that the OMAP uses v4l2-int-device and the PXA uses 
soc_camera. Is the Davinci's VPFE like either of these?

3. Should I really be asking these questions in the video4linux list?

Thanks for any insight you can provide.
