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. ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chris Douglass Sent: Tuesday, November 04, 2008 4:05 PM To: [email protected] 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. -- Cheers, Chris Douglass [EMAIL PROTECTED]<mailto:[EMAIL PROTECTED]>
