Great news.
A new version of the ISP driver will soon be published with all the legacy
code removed. We need a few days to setup the repository properly. You can
already get a preview at http://git.linuxtv.org/pinchartl/media.git (omap3isp-
rx51 branch).

The OMAP3 ISP driver won't support V4L2 overlay directly. However, you can use
the USERPTR streaming mode and pass framebuffer memory directly to the ISP
driver, resulting in DMA to the framebuffer and improved efficiency.
