I have IMX6 boards in mainline (Gateworks Ventana product family) that have both composite input (adv7180) and HDMI input (tda1997x) via the IMX6 CSI and am wondering what is left to achieve mainline video capture on the IMX6. Video capture and crypto are the last things I know of that can eliminate the common need of a downstream vendor kernel with 100's of Freescale patches. Can you point me to the most recent git tree that you were working with and tell me what devices you were using to capture with?
