Hi all,
I have one question about capture with the OMAP3ISP.
I'm trying to capture images with the MT0V034 sensor included in the
IGEP Cam Bird with the IGEPv2 board. I'm using the 3.17 mainline
kernel with some modifications to register the sensor and configure
the pin muxes.
The sensor is registering correctly and I can configure the media
pipeline, but when I try to capture with Yavta all the system freezes
when Yavta try to queue the buffers, then the sensor is throwing data
by the parallel port, I can see this, but ISP seems don't get nothing.
This is the patch I wrote for this:

Have you some idea about what is not working? I think it's something
in OMAP3 ISP but I can't find the reason.
Thanks,
