It's a custom board with omap3630. ISP is not changed.
When I disable OMAP2_VOUT from defconfig "CCD output" is /dev/video2.
But result is the same - yavta sleeps at VIDIOC_DQBUF ioctl

Pipeline setup is:
$ media-ctl -v -r -l '"tvp5150 3-005c":0->"OMAP3 ISP CCDC":0[1],
"OMAP3 ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]'
$ media-ctl -v --set-format '"tvp5150 3-005c":0 [UYVY2X8 720x525]'
$ media-ctl -v --set-format '"OMAP3 ISP CCDC":0 [UYVY2X8 720x525]'
$ media-ctl -v --set-format '"OMAP3 ISP CCDC":1 [UYVY2X8 720x525]'
media-ctl output (with /dev/video4):
$ media-ctl -p
