I think you are missing the ccdc sink pad setup, basically you should
have something like this:
....
- entity 5: OMAP3 ISP CCDC (3 pads, 9 links)
type V4L2 subdev subtype Unknown flags 0
device node name /dev/v4l-subdev2
pad0: Sink
[fmt:UYVY2X8/720x288 field:alternate]
<- "OMAP3 ISP CCP2":1 []
<- "OMAP3 ISP CSI2a":1 []
<- "tvp5150 1-005c":0 [ENABLED]
pad1: Source
[fmt:UYVY/720x576 field:interlaced-tb
crop.bounds:(0,0)/720x288
crop:(0,0)/720x288]
-> "OMAP3 ISP CCDC output":0 [ENABLED]
-> "OMAP3 ISP resizer":0 []
with this setup i can correctly capture deinterlaced frames with
yavta, but have a look at the "[PATCH 00/11] OMAP3 ISP BT.656 support"
thread, i noticed some problems maybe it's the same for you.
