Hi,

i need some help to debug a kernel hang on an igep board (+ expansion)
 when using omap3-isp and tvp5150 video capture. Kernel version is
mainline 3.0.1

I found that this driver is not compatible with the [new] v4l2_subdev setup.
In particular, it does not define any "pads" and the call to
media_entity_create_link()
in omap3isp/isp.c:1803 fires a BUG_ON() for this condition.

So basically what is needed is to implement pad functions and do
something like this:

static struct v4l2_subdev_pad_ops mt9v032_subdev_pad_ops = {
        .enum_mbus_code = mt9v032_enum_mbus_code,
        .enum_frame_size = mt9v032_enum_frame_size,
        .get_fmt = mt9v032_get_format,
        .set_fmt = mt9v032_set_format,
        .get_crop = mt9v032_get_crop,
        .set_crop = mt9v032_set_crop,
};

and add media init/cleanup functions? Can someone confirm this? Is
someone already working on this?
