I'm using different board.

What board?  I would think the architecture of the OMAP3 ISP would
not change, based on the board?

It's a custom board with omap3630. ISP is not changed.
When I disable OMAP2_VOUT from defconfig "CCD output" is /dev/video2.

I see, I have that option turned off.

But result is the same - yavta sleeps at VIDIOC_DQBUF ioctl

How are you configuring the TVP5150?  In particular these settings at boot
time:

static struct isp_v4l2_subdevs_group my_camera_subdevs[] = {
        {
                .subdevs = tvp5150_camera_subdevs,
                .interface = ISP_INTERFACE_PARALLEL,
                .bus = {
                                .parallel = {
                                        .data_lane_shift = 0,
                                        .clk_pol = 1,
                                        .bt656 = 1,
                                        .fldmode = 1,
                                }
                },
        },
        { },
};

My settings are:
  				.data_lane_shift        = 0,
				.clk_pol                = 0,
				.hs_pol                 = 0,
				.vs_pol                 = 0,
				.fldmode                = 1,
				.bt656               = 1,

I tried yours but same result.
Why did you chose clk_pol=1?

I just copied the settings from the BeagleBoard

Have you had this working before (earlier kernel, etc)?

This is how you tell the ISP to run in BT656 mode.  Without it, it will run
using the HS/VS/FID signals (and also in my experience does not work
properly)

Should be /dev/video4...

Could you send your pipeline setup and full output of 'media-ctl -p'?

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):

Hi

I'm trying to run OMAP + TVP5151 in BT656 mode.

I'm using omap3isp-omap3isp-yuv (git.linuxtv.org/pinchartl/media.git).
Plus the following patches:

TVP5151:



https://github.com/ebutera/meta-igep/tree/testing-v2/recipes-kernel/linux/linux-3.0+3.1rc/tvp5150

The latest RFC patches for BT656 support:

Enrico Butera (2):
   omap3isp: ispvideo: export isp_video_mbus_to_pix
   omap3isp: ispccdc: configure CCDC registers and add BT656 support

Javier Martinez Canillas (1):
   omap3isp: ccdc: Add interlaced field mode to platform data


I'm able to configure with media-ctl:

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]'

But
./yavta -f UYVY -s 720x525 -n 4 --capture=4 -F /dev/video4

sleeps after
...
Buffer 1 mapped at address 0x4021d000.
length: 756000 offset: 1515520
Buffer 2 mapped at address 0x402d6000.
length: 756000 offset: 2273280
Buffer 3 mapped at address 0x4038f000.

Anyone with the same issue??? This happens with every other v4l test
app
I
used.
I can see data from TVP5151 but there are no interrupts in ISP.

Why are you using /dev/video4?  The CCDC output is on /dev/video2
