The OMAP3 ISP driver doesn't use the deprecated V4L2 int-device API anymore. The latest version of the driver can be found in the omap3camera tree on gitorious (make sure you checkout the devel branch). > Also I got know that there are there are 3 different frameworks for camera > sensor drivers in Linux > a.

The soc-camera framework isn't deprecated, but it isn't used by the OMAP3 ISP driver either. > 3. What is the best option/recommendation from community for me to integrate > MT9M112 with Camera ISP system on OMAP 3530 based board ? The dependencies on the soc-camera framework in the MT9M112 driver need to be removed. I've CC'ed Guennadi Liakhovetski to this e-mail, he's the author of the soc-camera framework and should be able to provide information on what is required. > 4.

Not that I know of, but there's a video decoder driver (tvp5150). -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
